I know that changing your oil is one of the easiest and cheapest ways to maintain the longevity of an engine but i am curious what the repercussions could be for not changing your oil for an excess of 8000 miles a few times. I am looking at buying an infinity g37x (AWD) and the previous owners oil change tendencies caught my eye. Would this be a deal breaker for you? Or perhaps if the price is right?
Experienced mechanics share their insights in answering this question :
Changing engine oil on a regular basis is certainly on way to have a long healthy life with your engine. For most model years, Infiniti recommends "normal" service intervals of every 6 months or 7500 miles, whichever comes first. So long as the vehicle wasn’t used for towing or in a dusty environment – where Infiniti recommends the oil change intervals be cut in half to every 3 months or 3,750 miles, – running 500 miles over the recommended interval shouldn’t cause any real issues. It is difficult to predict whether or not any issues is really uncertain. Issues can crop up with even the most meticulously maintained vehicle.So long as the oil level was checked between oil changes and topped off if needed, the extra 500 miles on one or two oil changes should not really effect the health of the engine.

With this or any other vehicle, if time constraints keep you from getting the oil changed on a regular schedule, have a certified technician come to your home or office to perform an oil change at your convenience.

Specialized synthetic oil: Most Infinitis require synthetic blend or full synthetic motor oil—and synthetic oil changes usually cost more than conventional motor oil. The exact price will vary depending on the synthetic oil used. Oil filter cost: You may need to replace your oil filter when you get an oil change.
How Long to Go In Between INFINITI Oil Changes? Even though the new rule of thumb is twice a year or every 7,500 to 10,000 miles, it`s recommended that you should go about 3,000 miles in between oil changes.
When the oil change light illuminates, you should grab your car`s dipstick to check the current situation. But even before the oil change light releases a signal, you shouldn`t wait until your vehicle reaches that point, or it could lead to worse problems, such as the need to get an engine repair.
Whether you own or lease your INFINITI, you must remain up-to-date with your maintenance to keep your INFINITI healthy. But how often should you have your INFINITI oil changed? The general rule of thumb is twice a year or every 7,500 to 10,000 miles, whichever comes first.
With routine maintenance and service, you can expect your Infiniti auto repair cost to average around $600 a year.
Everything about it is expensive, right down to the oil change, which can ring you up a staggering $21,000. If you need some explaining on why a Bugatti Veyron oil change costs as much as a brand-new Honda Civic, then you`re not alone. The truth is, we live in a world where examples of excess and opulence exist.
Most INFINITI models can typically last up to 200,000 miles. The lifespan you can expect from an INFINITI car or SUV depends on: The specific model purchased. Whether or not the vehicle has been kept up to date with its maintenance service schedule.
How many years can an Infiniti last? With the right level of care and consistent maintenance, an Infiniti could last you as long as 15 to 20 years by some estimates. Key Takeaway With proper maintenance, your Infiniti could last more than 200,000 miles.
As engine oil ages, it breaks down and becomes less effective at doing its job. Most manufacturers recommend getting the oil changed at least once per year, no matter how few miles you`ve spent on the road.
“While synthetic generally holds up better and can serve for more miles, it is equally important to not extend oil changes beyond the time interval recommended by the manufacturer—typically six months or a year if it is a motor that is not driven many miles or on many short trips.”
Exposing the oil to moisture degrades the oil as much as running the engine hard for 5,000 miles. The solution is to flush all that stuff out with fresh oil every 5,000 miles or 6 months, whichever comes first.
Advantages of Frequent Oil Changes

By changing your oil at regular intervals, you help keep harmful particulates from damages to your engine, which can result in costly and significant repairs down the road. Regular oil changes help extend the overall life expectancy of your vehicle.

INFINITI is a luxury auto make originally from Japan. The luxury brand was birthed in the year of 1985 at Nissan Motor Co. with the hopes to bring more luxury, performance and sophistication to the day-to-day vehicle that Nissan was already manufacturing.
The upscale brand to Nissan, Infiniti offers a mixed bag of some stylish and some long-in-the-tooth models. Fit and finish is usually very good, and the powertrains are typically strong. Like most manufacturers, the brand has been focusing on supplementing its SUV offerings with the QX50, QX55, QX60, and QX80.
For several years, they`ve been named one of the most reliable car brands by J.D. Power and Associates and Consumer Reports magazine, which does extensive surveys on new cars every year from actual owners of those vehicles over extended periods.
Algeria, Equatorial Guinea and Angola crudes the most expensive in the world (OPEC)
Taking into consideration the above-mentioned facts, you might be amazed to discover that the world`s most expensive oil is Malaysian. Tapis, the Malaysian crude benchmark traded in Singapore, has for a long time held the title of the world`s most expensive grade.
We only use high-performance synthetic oil and high-performance, INFINITI brand oil filters, as these components can help maximize your vehicle`s performance.
The quick-lube chains usually recommend it be done every three months or 3,000 miles, but many mechanics would tell you that such frequent changes are overkill. Indeed, most car owner`s manuals recommend changing out the oil less frequently, usually after 5,000 or 7,500 miles.
Lexus cars and SUVs outperform INFINITI models in terms of reliability, according to the J.D. Power and Consumer Reports dependability ratings.
The INFINITI model that is the most reliable and ranks the highest in its vehicle category is the INFINITI QX50, which ranks 7 out of 29 Most Reliable Luxury Small SUVs. Following the QX50 is the INFINITI QX80 and the INFINITI QX60. You can see the rest of the INFINITI vehicles and their rankings below.
As a higher-end brand with decent reliability ratings, an Infiniti will cost you more than average to maintain it. According to RepairPal, an Infiniti`s average annual repair cost is around $638. When you`re looking for a new car, that sticker price won`t be the last car-related expense you`ll have to pay for.
Is Infinitis reliable after 100k miles? Many Infiniti cars with over 100,000 miles are still performing well. According to Nissan, you can drive more than 200,000 miles if properly maintained.
INFINITIs tend to keep their value over the years, so buying an INFINITI from our reliable dealership may be one of your best options.

Replaced alternator on car 2 times each time shows it’s charging 14v let car run for a little bit then test drive and car voltage
ANSWER : There are reports that the replacement alternators will not communicate with the engine computer and will not charge correctly. I recommend using only the manufacturer approved replacement part. It can be new or remanufactured but approved for use in the vehicle. Some lower cost alternators on the aftermarket will have charging problems since they will not communicate with the ECM on the vehicle and will stop charging.

Oil leaking from under car and "remote control car" sound when car is first started for a few minutes until it warm up.
ANSWER : Hello,
There are a number of things that could make an engine noisy when starting up. Depending on the specific type of sound you are referring to, this will determine how to properly diagnose. If there is a bit of a hissing sound, this may be a sign of a vacuum leak. If this is more of a shrieking sound, this may be a sign of a worn out or out of adjustment serpentine belt. If there is a bit of a howling or growling sound, this may be a sign of a worn out or low on fluid power steering pump. A rattling or pinging sound may be caused by an ignition problem. An engine can ping (or knock) due to an improper combustion process. A "spark knock" is the result of combustion occurring too early. Early combustion can occur from carbon buildup inside the combustion chamber, a lean air/fuel mixture, and advanced ignition timing (spark plug firing too soon). A clattering type sound may be a result of improper lubrication in the valve train which could be a more serious problem and should be addressed as soon as possible. I would suggest having an expert from YourMechanic come to your location to diagnose and inspect your vehicle to ensure everything is in proper working order.

Battery and oil light come on when trying to start car, take keys out try again car starts no problem and lights go away
ANSWER : Of course, don’t switch gears without being fully stopped, unless your Owner’s Manual or the manufacturer has alternative advice. However, the gear shift issue has no relation to the no-start problem you are describing. Inasmuch as you only have 6,000 miles on the car, the "constant on and off" that you believe has occurred is meaningless in comparison to the expected total vehicle service life. That is, assume what you perceive as "constant on and off", during merely 6,000 miles, might be equivalent to using the car "normally" for three years. A new car should be trouble free for at least 5 years, unless there is a defect, so your "constant on and off" is not a causal factor for any fault on the vehicle. What you might have is a defect in the ignition switch, or perhaps the immobilizer system, but if the problem is not in the switch itself, clearly there is an electrical problem.

If your vehicle is under warranty, by law the dealer MUST repair the issue you are describing within a prescribed time frame and number of "attempts", otherwise the dealer will run afoul of Federal and state Lemon Laws that give you very specific rights, and recourse (contact an Attorney; we are Mechanics, NOT attorneys). Consequently, if the vehicle is still under warranty, to save yourself money do be sure to seek a resolution from the dealer. If the vehicle is not under warranty, obviously a certified Mechanic from YourMechanic could identify the electrical fault and resolve this for you. If you want to go that route, please simply request a no start diagnostic -electrical system and the responding certified mechanic will get this taken care of for you. If you have further questions or concerns, do not hesitate to re-contact YourMechanic as we are always here to help you.

I will buy a car in the US, and has the powertrain fault indicator on. Is it cheap to fix it?
ANSWER : YourMechanic can dispatch a certified Mechanic to personally inspect the vehicle in the U.S., in a pre-puchase inspection and e-mail a complete report to you. The report would note the specific Diagnostic Trouble Codes associated with the Powertrain issue that you are referring to and the associated "possible" parts in need of replacement. However, to get a conclusive estimate of the cost to repair the powertrain issue (i.e., your specific question) requires an actual diagnostic such as a check engine light diagnostic. Inasmuch as the vehicle is damaged, such a diagnostic is a little risky in terms of reliability because diagnostics are typically done on otherwise fully functioning vehicles. I recommend you go the inspection route, that is obtain a pre-purchase inspection. Unless the price on the vehicle is unbelievably low (indeed close to its scrap value) buying a collision damaged vehicle remotely, without a comprehensive, authoritative and complete report on its present condition is not wise. If you have additional concerns, questions, and/or wish to schedule a pre-purchase inspection, we are here to help you.

Power steering loss, no belts are turning but the car is running fine. I also have a soft pedal. Whats wrong with my car?
ANSWER : I have only seen this situation once in my 30+ years and it turned out to be a broken crankshaft pulley. Belts are driven by the engine. The crankshaft pulley spins the belts, which in turn spin the air conditioner compressor, power steering and water pumps, and the alternator. The vehicle should be towed to your local repair shop and not driven. Without the water pump spinning to circulate the coolant, the engine will quickly overheat and result in more extensive damage.

My car will not start Intermittently. I purchased a new battery 2 weeks ago and yesterday the car wouldn’t start. Got a jump and
ANSWER : The issue you are having is probably due to an intermittent fault in the starter motor itself or a deficiency in the starter electrical circuit, for example a large voltage drop due to a poor ground or a high resistance connection. These issues can be readily diagnosed and resolved on a mobile basis if you request a hard starting diagnostic. If you request that diagnostic, the responding certified mechanic will get this resolved for you promptly. Based on Toyota’s Factory Service Manual, the battery should not be disconnected if the vehicle engine is running. The battery acts as a large resistive voltage sink and consequently taking the battery out of the circuit, while the alternator is still running, can create a voltage spike on the car’s electrical system which is not good for voltage sensitive components such as the engine computer. If you have further questions or concerns, do not hesitate to re-contact YourMechanic as we are always here to help you.
