No need to be a dealer to get these dealer prices. Just do the preferred customer thing at these instructions. http://www.modernoils.com/Purchase_at_Dealer_Cost.html This makes it super easy to get AMSOIL at dealer cost which is generally 20-25% off retail prices. I believe shipping is only about $8.50 for a case and since it goes by the pound with lower rates for larger orders you save quite a bit in the long run.

Thanks for all of the information on the Amsoil products. Ok, I am really confused on what I need for my specific application. I have newly built 540s, 700 hp NA, plan on about 20-25 hours between oil changes. Currently, have the break in 40w Valvoline racing with Wix filters (12 hours). If I were choosing an Amsoil product, which one would you suggest? Typical boating, a little racing and a little cruising. WOT @ 5800.

Amsoil ARO 20W-50 is the one that will fit your needs best especially with 25 hour changes.

Your mills will do great as I know guys who use this and get great results. No sludge. Instant pressure on start-up. The right oil temps.

Use with confidence.

Is there any oil either Mobil or Amsoil that would be good for 40 hours (my entire season). I am asking this to determine if there is any oil that you would feel comfortable leaving in for the entire season? If not, I will stay with Mobile 15w-50 or Amsoil 20w-50. Thanks.

Hydrocruiser

Either of those products you mentioned would do fine out to 50 hours.

Thanks for the comments and suggestions, but I'll have to wait a couple of years to make the change to synthetic. My engine builder said he won't warranty the engines if I don't use Valvoline VRI 40. The warranty means a lot in the world of performance!

Your Valvoline VRI now comes in synthetic...I would show your builder this as it is the exact same formulation of additives etc. but has a stronger base and is rated 20W-50 for faster starts and better heat protection at the top as well.


By the way folks..this is real close to M-1 V-Twin in ZDDP levels...gotta be a great product and one I would try.

Thanks for the information, I'll pass the information along. Another question, I am now using 70w-90 Amsoil in my Bravos. Is this a better product than the Mercury lube? It seems pretty thin, but I've read where others have been using.

Hydrocruiser

If you ask the Amsoil guys who have a booth at OSO races they will tell you not to use the Universal Marine lube in an "offshore rig" but to use Severe Gear...I think the Marine product is nice for a runabout but too thin for offshore applications as well.

Asmoil made a mistake in my opinion of discontinuing their Series 2000 Marine gear lube. I know Teague liked it a lot as did Imco.

Go with this stuff below is my call as it is what your drives need...High Pressure Lube Additives..aka ZDDP and plenty of it.

Severe Gear seems to be a cut above the green stuff.
