Why don't you do a little research on consumer protection rights before you go spouting off misinformation.

 

Any time after the initial few thousand miles is fine. Enjoy.

Please tell me where I've "spouted misinformation". I have made no claim that Infiniti would or wouldn't provide warranty coverage...that's YOUR thing...all I've said is that I think SeattleG should contact Infiniti to ask THEM.

Why do you have your panties in a wad?

 

i think its ok to switch to synthetic after atleast 15K-20K miles...i switched at 15K

 

Switch to Mobil 1 at 3700, 1st oil change....and using Mobil 1 oil and filter....changed oil again at 7900

whatever man...if u want to do it...do it....

 

I am at 2300 miles and going in at 3500 for an oil change. I bought this car and expect to have it for more then 100,000 miles. What is the benefit of switching to synthetic oil at 3500 miles? Will it cost me more money and is it really worth it?

 

Syn. doesn't break down (TBN numbers....additive levels) under heat or pressure like Dino oil. This has been a known fact for years, but for some reason slowly accepted...much like the concept of the earth being round. "Breaking-in" an engine on Syn. is PERFECTLY frigg'n fine. Costs more? ...sure does.....so did your car vs. a Kia, even though they both do the same job of getting you from point A to point B.....It's just the difference in how they do it....no?

 

OK, after this I'm going to let this go because this isn't productive at all.

I made the statement that he should use whatever he feels comfortable with. You said this is bad advice. Fact is, any oil he gets his hands on will be just fine for the G35 or any other car for that matter as long as he maintains the same weight be it synthetic or not.

There is no voodoo magic or witchcraft in synthetic that will be detrimental to his engine at any mileage for break in I ASSURE you. But there I go again trying to present myself as an "Infiniti Tech"....

 

Thank you JBX. Well said.

 

I ran synthetic in my old sentra for the last 8000 miles before I traded it in (had 34k on odo when I did) I switched to Mobil 1 at around 6500 miles, and I currently have about 10300. No lookin back either!

 

No, I'm sorry but your wrong, again. "Any oil he gets his hand on" ISN'T fine, not when discussing warranty coverage.

And since I want the correct warranty answer myself, I looked it up in my OM and Warranty Booklet. It's a 3 parter.

1) OM calls for oil to meet API requirements (basically SL or better and Energy Conserving Class 1 or 2, open your OM if you want the actual list) and "recommends mineral based oil. But they must meet API requirements..."

2) Maintanence intervals must be followed for warranty to apply.

3) Owners must be able to provide documentation of proper maintanence to make a warranty claim. Failure to provide documention will "Likely" result in warranty denial.

The strictest interpreation would be "only mineral oils meeting API service requirements can be used." This is clearly not the only interpretation since the API requirements is the primarly condition to be met.


Warning, opinion below:

For warranty coverage to apply, we MUST comply with service intervals (for most of us Schedule 1...oil change every 3750) AND we must provide documentation of maintanence (save reciepts for those who do own maint.)...there is no significant benefit to synth. over mineral oils.

As you point out, there is no voodoo magic in synthetic...using it in such a short interval only costs more money. I've read a lot about oil and have seen no convincing arguement that synthetic is better than mineral oil in the time intervals being discussed (3 months or 3750 miles).

There may be some value if you are a Schedule 2 driver or other individual circumstances.

 

Dude...with your attitude you're gonna need a flame retardant suit. Everyone here can read quite well, I'm sure. And, are quite aware of the minimum requirements regarding PETROLEUM based oil. Further more Einstein, why does most EVERY Infiniti dealership offer synthetic oil for your "required service intervals"????? Considering that I've probably driven backwards further than you forward, and that I've probably tore-down and rebuilt more engines than you've turned pages in your frigg'n owner's manual......I feel qualified to say you've gotta lot o' research to do before you make such blanket verbal assumptions. Use whatever oil ya want, or can afford, just get a clue and save the condescension for people who deserve it.....they're not here. Much luv,JBX

 

Okay I've seen lot's of post on this but nobody ever answers the question as to why is synthetic better? It's becaue sythetic is man made to specific tolerances. The oil molecules end up having a more uniform size so you actually get more oil between the metal surfaces. It also breaks down slower and will hold up better at higher temperatures. I have a '93 Jeep Grand Cherokee that holed a radiator. While trying to get it home it got so hot it stopped running. Yes I was using Mobile 1 and yes after fixing the radiator it runs just fine.
Now If you don't thrash your car you may never need synthics extra protection and your car may be fine. But for me it's worth the money and peace of mind to know it's there.

 

Nice job ZGUY, You've also got a higher additive level (True Base Number) and better liquidity at extreme low temperatures to consider. Good factual explanation for the flat earthers.

 

First, your reading attitude that isn't there.

Second, the question as ASKED whether switching to synth. would affect warranty coverage. The answer is: It doesn't, provided you use the proper API service, viscosity and change interval. (which explains why dealerships offer it) The answer is NOT: "do what makes you comfortable" or "any oil of the proper weight" or "I think it's ok if..."

Third, to what blanket assumptions do you refer?
