FOr those that are currently running Amsoil products in your 928, what spec are you using in the engine????

I finally have a local source for Amsoil, and have been thinking of switching over from Mobil 1 15-W-50. TIA,

I have always used 20-50, but with Doug H's info, I may switch to 10-40 or something a BIT thinner.

I stopped running 20w50 and went to 10w30, I will also try 10w40 next to see what the car likes best.

Chris,

I use the 20-50W. I found that if I use a lighter weight oil, it seems
to disappear faster. Also the oil pressure drops more when hot
with the lighter weight oils.

Depends on what your running and how fast. Reading Doug's write up i went to 15w-40 for warm weather running for the best viscosity IMO.

I use the TRO2000 20w50 racing oil.

Actually placed the order for this season last night. 4 gallons and 6 quarts for $148.10. Have 3 quarts in the garage which should cover changes on my 928 and 944 along with spare quarts for topping off between DE sessions.

I like it because the oil pressure stays up during hard track use. This is not the be-all of wear prevention, but it does give peace-of-mind with regards to the bearing failure. No engine camera mounted, but the Amsoil is supposed to foam less and mist less and that is important to keeping oil flowing to the bearings.

20w-50 racing. I used Mobil 1 previously. I would blow the M1 quickly at high rpms. Not so with the Amsoil. I do see higher pressures with the Amsoil.

20 50 racing, same as Glen. good pressures, no particulates in the oil filter after 3 race weekends, 3 full seasons, and seems to be a "kind of " cure to the 2-6 bearing issue. (or some darn good luck)

Cool. Thanks for the responses guys. 20 w 50 it is!!!!!!!!!!!!!!!!!!!!

The Amsoil 20-50 Race is specifically made for track use only (just read the label). Good stuff, but not for street use.

Chris Lockhart

So which weight would you suggest for the street John? 10w40???

John Veninger

Amsoil makes a TRO 20w-50 and an ARO 20w-50. The ARO is what their site states as a street oil.
I use the TRO in the track car and run Syntec 5-50 in the street car. Was using M1 in the street car, but switched a few years back due to a nice price break on the Syntec

I am switching from Quaker State synthetic to Amsoil 5w-40 up here in colder New Hampshire. I have a friend who plans to come out to the shark meets as a passenger to hang out who is a dealer for Amsoil. Fortunately for me, he has good stories, is very knowledgable and is entertaining. I have considered using their motorcycle 20w-50 when I put the SC on my shark.

Oh, yeah. The "V-Twin" Amsoil. Gotta wonder how that's different then the regular automobile 20w50. I've topped off with that when my weekend supply ran short. It's available at "Fleet Farm" is these parts.

Also, gotta wonder why they don't recommend the racing oil for street use. My first reaction is marketing to emphasis the special nature. I run it all the time, just don't run the car in the winter.

I can understand the straight-weight oils be street-only as a 50W oil would be awfully thick when cold. (and that's nearing zero in my book.)

Marketing IS everything to an oil company
