New 2005 Maxima Owner

Change oil to Mobil 1 5/30 use only Nissan filters.

I have also just bought a 2005 SL and have the same kind of questions.

Is there a break-in period?

Why Mobil I 5/30

Are the factory installed tires okay or are there any better ones? I live in NW PA and it can really cold and icy as from November.

Please any words of wisdom , Nisstech?

Thanks...

Why Mobil 1? I know it's a synthetic but oil these days have an additive package that makes them "almost" as good. Synthetics do have the advantage of superior high temperature oxidation resistance, high film strength, very low tendency to form deposits, stable viscosity base, and low temperature flow characteristics. But is it worth the extra $5+ a quart? How often is oil changing recommended with Mobil 1?

Dr. I can't answer the tire question. Mine came with Goodyear Eagles. Being front wheel drive I'll assume any all weather tire would be decent in snow. So far some research has me leaning toward Amsoil if I go synthetic. The

10,000 mile interval between changes kind of justifies the cost..........maybe:)

And probably voids your warantee. Don't you have to change every 7500 (or whatever Nissan requires for your model)? No warantee worries for my Max with 150k miles though...

Interesting question about the warranty. I'll have to check that out.
