I havent nor do i know anyone who has used
Amsoil. However I have used Mobil 1 and Royal Purple and would reccomend either of those if you are lookin for a syn oil. Id put Royal Purple at the top but it is a little pricey even compared to Mobil1.

synth is a to smooth to carry contaminants to the filter.

I wouldnt use it on a dirt stock car motor.

thats just me.

i read that too a couple years ago in stock car mag an engine builder from cup said not to run syn oil in dirt cars because it don't carry dirt as good as crude based oils

as far as i know, modil 1 is only semi synthetic. redline and royal purple are 100% synthetic.
redline told us that alcohol isn't a problem assuming your engine is tuned well and doesn't fuel up big time. they said any moisture or alcohol in the oil will evapourate away with the temperature of the oil. the only problem is the cost, especially with the volume that a dry sump will hold.

Been running synthetics about 2 1/2 years now and haven't got any complaints.Ran mobil 1 15w50 and switched to royal purple 15w40 last year and just tore down for off season rebuild and like what I see or don't see.This motor has 3 seasons on it now and everything is the same parts as the original build.Acually the bearings looked better this year than last.The rocker fulcrums show less signs of heat.I change every 3 races and filter evry race.This is one of the only things I get donated to the cause.

Whether you choose to use AMSOIL or another synthetic oil, there is a wealth of information on the benefits of synthetics versus dino oil on my website...if you care to have a look.

We started running Amsoil in our Wissota Streeter Last year. Ran 0W30 and ran 32 shows on two oil changes,we changed the filters at 6-8 shows depending on what the oil looked like. We are very pleased with the results. Cooler Temps, and a couple 350 + degree breaks in the cooling system. We tested this oil through the Lab that we send our DOT oil to and is is very good on breakdown, etc. at the end of season we miced our bearings and 1 thous. wear on the mains and about 3/4 of a thousandth on the rods. I will run nothing else in any of my Chevys.

I ran Amsoil in my 355 from May - Sept last year with 2 filter changes (the high perf. 20w50). Had a cracked/pitted block and ran 250+ degrees just about every race all year. When I tore the motor down, everything was perfect. No abnormal part wear even with the excessive heat. I even ran a 30 lap race the last weekend of the year with the temp gauge pegged at 270+ for 16 laps.

Gets my thumbs up.
