Mileage
I have a 1998 infiniti I30 and have a question for all of you 4th gen. owners. first whats the highest mileage (odometer reading not gas) that anyone with a 4th gen has and also what are the pros and cons of synthetic or synthetic blend oil. I surrntly use conventinal oil and probabally always will in this car i also have 75000 miles on mine but im sure that somone here has many more miles on theirs.
just curious

I sold my 96 with 129 on the clock...it was conventional oil its whole life....it didn't leak or burn a single drop between changes every 3K. Compression tested right in the middle of the spec, and was even. It even ran head to head against my newer 99 with half the miles...a dead even race....not bad.
Unless you are really pounding your car, or in a really hot climate, sythetic isn't going to pay you much back....the engine will run 200+K without so much as a hick-up on parts like main bearings, rings, pistons etc. Unless you do extended intervals, like 95MaxSE, you are wasting your money...in my opinion.
The tranny was switched over to synthetic at 100K...which I will highly recommend though.

well...not sythetic oil...but synthetic ATF. Most people here use Mobil 1, Redline or maybe Amsoil brands.
Synthetic ATF is 2.5 to 3 times the price of regular ATF. But since ATF stays in there for 30K and tranny failures are more common than internal engine component failures its well worth the money to me.
The properties of sythetic ATF will give you more consistant shifts be it hot or cold and it will also help soften some of the harshness in the shifts. As with engine oil, sythetic ATF can handle higher heat than regular ATF without breaking down. Synthetic will offer lower frictional loses too...which equates to better efficiency and less wear (you probably won't see significantly better mileage at the pump though).
Doing a full fluid change in the tranny is a little more complicated than changing your oil...but not much.
