First Oil Change - Brand New G35x

[g35at]

I have 500 miles on a brand new G35x. When should I perform my first oil change?

Also, should I switch to synthetic on the first oil change , or wait until about 10-15K miles?

Thanks for the help!

Welcome to NICO!!

I would change at 1k to get rid of the break-in oil, then again at 3k. After the second change, a normal schedule can be followed. Any oil that goes into the G should be synthetic. I recommend Royal Purple.

I have been hearing that you should wait on the synthetic until the engine breaks in. Is this a myth?

I think it is a myth... If synthetic oil is better why would waiting be helpful?

1+ for the royal purple!

You will really notice the difference!

The only time dino oil is recommended is the initial break-in, the first 300-500 miles.

Check out the bible: http://www.carbibles.com/engineoil_bible.html

There is some basic validity to the "myth".

I think Royal Purple even makes a break-in oil. The theory with engine break-in is that there needs to be a certain amount of cylinder to piston ring friction for proper seating. An overly slick lubricant MIGHT possible prevent that from happening and cause the engine to never seat properly.

I would switch to synthetic by the 1st or 2nd oil change.

Everything he said +1

On new cars I usually do the first oil change around 1000 miles and the second at 2000 miles. The first couple oil changes is when most of the wear should occur as the motor breaks in.

welcome to NICO

+1 synthetic i changed over on my 2nd oil change

[g35at]

so change the first time at 1,000 miles on dino oil, and then, when should i make the change to synthetic? At 4750 miles? Will it hurt to wait until my 3rd oil change to switch to synthetic?

[gwoods]

On my cars I change to Syn at 1000 and then do the first Syn oil change at 2000 but I'm crazy

The more the better IMHO at break in time!

Nobody told me I have to change my oil?! I'll be right back. Gone for oilchange. LOL

I have just over 1K. I have an appointment next week to change oil.

a local dealer states that the oil doesn't need to be changed for the first time until 3750...is it actually necessary to change oil at 1K miles??

Read the section on maintenance intervals in the Service & Maintenance Guide. It recommends 6 month / 7,500 mile oil changes if almost all your driving is long highway trips. Otherwise, the recommended interval is 3 months / 3,750 miles.

An underlying assumption is that the car is being driven nearly every day. If not, things get more complicated. Consider two extreme cases. One is a college student whose school is 90 miles from home. Since he lives on campus, the only time he drives is to visit home one weekend a month. The other extreme is a senior citizen who drives 3 miles to the senior citizens' center every morning and 3 miles back home every evening. After 3 months, each will have accumulated 540 miles. There is no way the student needs an oil change every 3 months. Changing annually might be more often than necessary. On the other hand, the senior's car definitely needs oil changes that frequently since it sees the worst possible service.

I'm not convinced that an Infiniti in typical street service needs synthetic oil. Infiniti delivers it with conventional mineral oil and the manual does not specify synthetic. Some manufacturers, typically German, do specify synthetic. Porsche Cayman oil is 0W40 Mobil 1, period. Porsche used to recommend oil changes every 2 years / 20,000 miles. They have now dropped this to 12 months / 12,000 miles. Some of the owners on the Cayman Club forum (www.caymanclub.net) have been sending samples to Blackstone Labs (www.blackstone-labs.com) for analysis. The results suggest that Porsche's 12/12 recommendation is not too long. Blackstone's business is diagnosing engine problems based on oil analysis and recommending maintenance. Because of their large customer base, they have a lot of experience with oil problems and oil life expectancy. On their web site, they mention that they use mineral oil, not synthetic, in their personal engines which power everything from cars to lawn mowers.

Engines run cleaner and oil is better than it was 30 years ago. Back then, I worked for a company that had its own oil lab. One of the unofficial fringe benefits was free oil analyses. In those days, 3 months / 3,000 miles was the standard oil change interval. After the lab people showed me that my car's 10W30 mineral oil was still in good shape after 6,000 miles, I stopped worrying about it.

My $.02 is if you are paying to have it done follow your owners maintenance schedule and perhaps let the dealer do it for you & enjoy their snacks and free car wash. Be careful of independent shops especially Jiffy Lube.

The best option is to do it yourself & purchase oil & oil filters on sale.I did change mine at the first 1000 miles and at 3000 and every 3000 to 3500 since. I did my 22nd oil change a few weeks ago and I generally use Pennzoil or GTX

Telco,

I want to buy some amsoil and a dual filtration setup for your car, then do oil analysis every 5k miles to show you how much more could be going into that 401k of yours.

Unfortunately, you'd probably forget how to do an oil change because of the extended drain intervals

Ok, perhaps when I'm older & no longer feel like crawling under my G

I've been doing this for over 40 years & got over 200k miles out of a few previous vehicles.

I have speakers in my garage & usually listen to Howard Stern while doing the oil change. The wife usually leaves me alone because she hates Stern.You'll understand after you've been married as long as I have.

The wifey recently got on my case about how I was driving and I blew up at her. She let off the subject and got really nice and friendly shortly thereafter. Not sure what this phenomenon is, but I'll be sure to do more testing.

BTW, my I30 (on it's 4th owner-not me) should be pushing 300k right now. Not sure what happened to it from 0-80k, but from then to 200k, my mom drove it and did Jiffy Lubes on a semi-regular basis. I beat the crap out of it from 200k-280k and did extended drain intervals. An exhaust leak and some valve chatter were the only drivetrain issues that existed when I sold it.
