Ok, the crusin wagon is about ready to hit the road again, Last year in sept. was hot rodding around and blew a hole in num. 4 piston. Months and months of waiting for new pistons, rings and bearings, and the guy who was rebuilding the head, new cam also, the engine is on the hoist waiting to be dropped in in the next day or so. It depends on how good the salmon are running up the local river. It opens to fish tomorrow, and I addicted to fishin.
Now the question, with all the multi grades, synthtic oils whats the best option. Or should I stick just to good old 30 weight oil.
Any input guys
Thanks
This is a good question! I am curious what everyone's opinions are too!!
I know people swear by it on the m/c forums. I actually use it on my Honda now, but haven't used it long enough to have an opinion on it yet! I am using Amsoil in the Honda.
I have heard that once you switch to synthetic you shouldn't switch back and forth, you should stick with synthetic. I don't remember the reasons for this though!
Looking forward to hearing some opinions on this!!!
Synthetic Promotes a longer engine life, Breaks down a lot less then Conventional motor oil, it just holds up better to the stresses of driving. i personally use Royal purple in performance cars and Valvoline Synthetics in everything else.
i too heard alot about that amsoil that pintogirl mentioned. i just use a conventional 10-30. my car is still VERY fat under boost so until i get the tune right, ill just change the oil alot with conventional. once its set and theres no leaks, ill probably switch to amsoil.

I've ran either 30 or 40 weight Valvoline for years. I had a 1991 GMC 1/2 ton with a 4.3 and auto. The truck had 40,000 on it when I bought it. When it was stolen at 260,000 miles after 9 years of owning it, it still used only 1/2 quart of oil between changes and got 19mpg. The block was still clean with no sludge....so as you can see I still use Valvoline today in everything I own.
you need to run conventional oil for startup and breakin. this will allow the rings to seat properly. if you run synthetic it will not seat the rings and you will have blow-by on your fresh rebuild.
