i know its expensive took a buddy of mine to buy a case at the local dealer, the dealer is a damn lawer. he has a 02 ws6 trans am witha built 402. 550hp at the wheels. he swears by the stuff. and still changes the oil every 3000

 

damn,i can't afford to do it every 3000,but then again its just for a diesel,getting ready to purchase gear oil's for my newer chevy...i like what im getting so far...as soon as i change my oil run around the block check it and it's black black...first time i did that as a new diesel owner i freaked out....ohhh ok it's normal

 

i wish i opted for the duramax damn near got a 4x4 dually fully loaded for 30,000 brand new. but i aint paying 500 a month.

 

went to get my new truck had it all picked out...gasser ..while driving to get my new truck, drove past a lot that had one that was ordered and not picked up....i knew i could not afford the d-max package but after messing around for 5 hours in there i drove home in it....now the fun part...my credit isn't perfect and so my huge payment eack month reminds me i better love that truck for a long time...but a killer truck ...i wanted a dually they are bad a** in my opinion...along with a bad a** sticker price...

 

Quick answer: Yes you can use the oils you currently have now safely.

Long answer: I'm doing my own field test RIGHT NOW to help answer a lot of FAQs about synthetic. I installed AMSOIL 3K miles ago, and the only final conclusion I've come to at this point is their oil filters SUCK, and I'll never buy another one.

 

what was your test performed on..gas/diesel/wvo ?what were some of the things you did not like about or get from it what you expected.is the micron's in the filter not enough?..i love field test...expand!

 

Umm, oil, yea. its good stuff isnt it.

 

mmm mmm good

 

Microns have got nothing to do with it.

The AMSOIL filter has no grip edges at all, it's slick and round.

When you think it's on tight, it backs off, and starts spewing oil.

That's how amsoil gets you for another three quarts on your first case.(Of course, for the next oil change, ya gotta buy another case...)

Next time I'm going to install a K&N oil filter. Maybe I'll tell you about the "Microns" in that one.

As far as the test, it's just one gas engine, a 6.0L in a Silverado 2500HD-4X4-CCLB.
It's been 3000 miles, I thought I'd try for 24000 miles, but I'm monitoring it as the "private field test" continues, if the oil pressure drops, or the oil reaches a condition which in my
opinion is not safe, I'll take it from there.

 

rivereye i would like to thank you for this usefull post...i run amsoil in my trucks and thought i would try there oil filter....i have been getting pissed trying to figure why my filter has has a very small drip that emerges,whiped it off tightened it thinking maybe i was lazy on the change...to this day it's still giving me a headache...so as for amsoil oil filters...(NOT FOR ME ANYMORE)....let me know about the other filter test as i am almost ready to rid my truck of this headache...
