there is a thread about amsoil on peoples opinions i personally run rotella t9 syn alot of people seem happy after they switch and get better oil psi others swear by amsoil
Amsoil FTW... LOL im not on the Amsoil band wagon but I have had good luck with it so I have kept using it
I switched to amsoil, scattered two engines. Now did that cause it,,,, not sure but I'm not one for taking chances again and that was the only thing I did different and the only engines I've completely blown to pieces. Got away from Amsoil haven't ventilated a block since

I was in Republic Diesel the other day an seen that Lucas has a 15-40 on the shelf, I don't know if its a new product, but it's new to my area, I think I may give it a try.
If your using Amsoil an it cost $110 a change but u change it every 25000 miles don't that save u money???

25k is under damn near perfect conditions with a stock truck.
Obviously the higher HP there is more soot getting in the oil, making it dirty and black.
I dont think anyone here would go 25k miles @ 500rwhp..
I buy Delo 400 15/40 at Walmart for $8/gal. last month on sale synthetic and just like MoBil 1 same company etc. I run it 100 hrs. and change it by hrs of service. So I spend $20 for oil and $10 for a K&N oil filter. No issues and you can buy many great synthetic or dino oils or a good price compared to the hi priced listed ones you see in the market. I change my fuel filter 200 hrs. of service and run a gallon of 2 stroke oil to 32 gals. of fuel also I should mention. Truck has never been to dealer 6 yrs. now I guess.
Amsoil 15-40 should not cost that much, get ahold of a dealer or become one yourself. i did it 6 years ago and never looked back!
I was commenting on the original response the guy that started the thread had said, I don't use Amsoil...I change mine every 3000 where it needs it or not..:thumb:
I run Delo 400 in everything I own from diesel trucks/tractors/equipment to gasser trucks/cars to dirt bikes/quads/law mowers. Awesome oil. Have a Chevy 350 with 400K on it and still running strong never been rebuilt and a Chevy 400 with 550K still running strong never been rebuilt. Just change the oil every 3K miles or 3 months religiously and run Wix filters.
Exactly what they want you to do. So you can spread information that only your catalog tells you
