dont have to use synthetic oils. However if you choose to, definitely go with a top dollar brand, something like Mobil 1 full synthetic.

i dont think it would make a differnce, but i would stick to what you use as premix so you dont get some wierd chemical reaction between two different oils as they cycle thru the engine, also were in louisville do you live, i spent about 3 years in that fun city

fun city? don't understand what you said

why would the oils mix? I removed my OMP. I was just wondering if synthetic would help the the engine last alittle longer, than use walmart 2 stroke for lubricating the apex seals and shizzle.

Don't bother.

Mostly, because you'll be getting somewhat increased blowby with premix, and should gain about a quart of oil every 2000-2500 miles. You'll want to change your oil around then, and if you're changing the oil every 2k miles, synthetic gets really expensive. :-)

Matter of opinion. I have $$$$$$$$.$$ invested in my car. I can afford to buy Mobil 1 for my turbo and engine every few thousand miles.

Castrol Syntec, the only way to go. I run it in both my Chevrolet Blazer S10 and my TII (which is premix)

If you can afford it or are just very particular of your oils. than buy synthetic. If not than standard mineral oil will work just as fine but dont forget to change it every 2500 - 3000 miles cause the oil molecules break down easily.

I have a friend who works for the Chevron gas plant and he says they do tests on gas and oil all the time and according to him you can run synthetic oil in your car for 50,000 miles before it begins to break down . Not that you would want to though. but just a fact to consider
