I am going to switch over to synthetic on my next oil change and was wondering if there was anything special i had to do. just drain and pour?

Yes just drain and pour. I like to use oil and filter from amsoil in the 20/50 weight for pushrod motors. Also synthetic's should not be used on a new motor. You should have at least 3K on a new build before this type of oil is place in

hey mike, where is the best place you know of to buy amsoil? Don't say you know where ![[Razz]](tongue.gif)
Any place online have it for a good cost? I'm running it now, and have read nothing but good things at this point, and oil change #1 is coming up.
Thanks! ![[patriot]](graemlins/patriot.gif)

Call them and ask for a dealer listing for sac/roseville area your car runs 5/30 weight or order directly at their web site

I wouldn't do it if your motor has much over 80k miles, because full synthetic can make every seal (timing cover, oil pan, rear main, etc.) leak when on conventional oil it wouldn't.
not for high mileage motors, IMHO.

I defeniately back this opinion every seal on your engine will more than likely leak i changed to synthetic on my old engine that had 105k on it and the next day on the garage floor it looked like my motor took a piss on the floor stick with regular oil if you have mileage on your engine beacuase regular oil is thicker and not prone to leak through your old gaskets. take it from experience

As I certainly will take these opinions into account I have a few other things I would like to mention. When running 20/50 weight amsoil you are running a heavier weight than the norm being 10-30 or 10-40. I think most people may run the synthetics but choose a lessor weight. I have heard this before but I have seen a good buddy of mine run the 20/50 on his 175K mile stock shortblock without any issues. This car has the stock oil pan gasket and stock rear main seal. Just a thought as I've used this on older cars for a long while now and have only this as proof. There may be individual cases where the above mentioned ideas are so, so it is a personal decision at this point for the owner

i've ran full synthetic in my chevy blazer that has over 200,000 miles, and had no problems. its a waste of money in my blazer.... but i just wanted to try it.
