I'd like to chime in on this oil change chat. I have been running SSO 0w30 from Amsoil also.(am a dealer too).and the wix filter. I mentioned it in another thread that I sent out a sample at 2 oil changes one with almost 10k on oil then again at about 8k. Both samples returned with dangerous amounts of fuel in oil. So now I am changing it more often. Can't verify fuel mileage because I can't keep my foot out of it. Have been avg. 20-22mpg. for a while now.

 

By the time you get to 8K you may be at 20% or less life anyway.

You will get some gas in the oil as that is just part of the way an engine works. You would be suprised how much can get in and not really hurt much.

We had a truck once with so much gas in the oil that it ignited. It blew the cap off and the valve cover gaskets out on the engine. We fixed the carb, changed the oil and gaskets. It only went on a 300,000 miles more before the cab rusted out. Then engine had never been opened up.

Too often the oil sample test can be a scare tactic for some oil vendors.
Engines are a lot more durable than some would like you to think to get you to buy thier products.

Unless there is something really wrong with your engine usally there is little worry about. Usally if there is that much fuel getting through you have a lot of black smoke or missing on a cylinder.

 

Just changed mine again today....love how easy it is.

 

Back in the radial aircraft eng days it was common practice to dump fuel in the oil just to start them in cold weather..the fuel thinned the oil enough to allow rotation and oil press to build..as it heated up the fuel would be burned/evaporated off....

 

They put degelling agents in them now along with lubricity additives.

 

Its a totally different ballgame now with aircraft engines and oil....they were still in the stone ages back then....
