An autozone worker recommend that I should add Valvoline oil treatment whenever I change my oil. Its only 4 bucks but is it worth doing or something that I shouldn't bother with?

 

Owner's manual, page 164.

 

I used to experiment with oil additives years ago - Duralube, slick 50, Prolong, STP.
It is my belief "THEY DO ABSOLUTELY NOTHING!"

 

PLEASE do not get the MUGEN additive, if I remember correctly it was around $50 a bottle. One of the biggest waystes one could make IMHO

 

without a teardown of the engine after every oil change, it is hard to say whether or not additives do anything for you. my understanding on them is that it breaks down cooked oil back into a fluid , so it can be drained duting the next oil change.
although it has not been really proven to work, has anyone proved it does harm?

im sure there are a lot of things out there that we can do to our cars that have no real effect on out cars, but we do them anyway to make our selves feel better.

comments guys?

 

Autozone? ... That should have been your first clue.

I recommend the Engine Rebuild in a can product myself.

You are right! If it makes you "feel" better, then the money is well spent. BUT, having tried all the "cure-alls" throughout my automotive life, I've learned not to "feel" right based on the money I spend. AND having gotten that lesson under my belt, I can't justify spending money (even though sometimes I still do) just because it can do no harm.

You are right!

 

i can't imagine that dino oil would stand up to the tremendous stresses of your engine components. If my memory serves correct, I read that "the stresses on the engine at 9000 rpm are twice that at 8000", or something very similar to that. I bet some of you are using synthetic and have no issues with deterioration. I know my oil looks "tar" black when I drain it at my 2000 mile interval. what kinds of products are you using to keep the stresses down......I'm amazed that there is little use of oil fortifiers.
