Using Amsoil=25,000 miles between oil changes?

[T-ROD]

Talked to this guy today, and he said he used some kind of Amsoil synthetic engine oil and he only changes his oil every 25,000 miles. He said every 12k or so he sends in a sample of the oil to Amsoil and has a test run on it and they always tell him it is still good and should keep running this stuff. I have a hard time believing any oil will go 25K. just wondering if any of you have any info. on this miracle oil? Sounds kinda strange but who knows.

Look up Shawn at Performance Oil Products. He can give more help then I.

I was a dealer for amsoil thats what they call for......believe me its the best oil out there and definately saves you alot of money!!!

They used Mobil 1 EP on a Porsche Cayman S to test out the oil. It lasted 100K miles. It isn't recommended but at that time, the Cayman had no issues. Just thought you find that interesting.

powerstroke has a hpop and that requires more changes.on a cummins that would be just fine i have done it with no problems but on a stroker i would never try it.you are just asking for hpop problems.

[etalian]

what is hpop?

[badazzstroker]

high pressure oil pump that is what drive the injectors on a powerstroke

So what's the max you can go on an oil change with Amsoil? 15K? 10K?

[badazzstroker]

i would say 10k would be just fine becuase it is synthetic.i run mine 5k on the old dino stuff.
