gear oil??????

at NAPA they have their brand gear oil (valvoline) and it says gl-3, gl-4, gl-5 safe......ok here is the stupid question......does that mean it can be used in my tranny (ax-5) which ive been told does not like the sulfur content of gl-5.........i know there is tons of stuff about gear oil on this site but nothing like the question i asked...

Re: gear oil??????

Does this help ?


Victory Lube Oil FAQ

What happens if API GL-5 gear oil is used in an API GL-4 gear oil application... ?
API GL-4 and API GL-5 products typically use the same extreme pressure (EP) additive system, with the API GL-5 having about twice the concentration of a API GL-4. In service, these additives become active under extreme load and temperature when the protective oil film can be squeezed away. EP additives work by forming wear-resistant compounds with the metal of the gear tooth surface. As the gears mesh, these compounds shield the gear teeth from direct metal-to-metal contact that would cause wear and damage to the gears. If too little of the active additive is present, proper protection would be compromised. Too much of this additive could cause excessive chemical corrosion of the gear surface. If an API GL-5 gear oil is used in a application where API GL-4 gear oil is called for, chemical corrosion of "yellow metal" components may occur, such as bronze synchronizers, brass bushings, etc. This may lead to shifting difficulties or shortened equipment life.

Re: gear oil??????

been thinking about what you said the Oil you were looking at had on it.... Good for GL3, GL4, and GL5 applications.... That doesn't mean that the gear oil you were looking at is GL3, GL4 or GL5..... they are apparently saying it can be used in those applications.... Is it much cheaper than a strickly GL3 or GL4 lube? or is that all that NAPA carried? What did they say about whether or not they GARUANTIED it would be Fine to use for your tranny??????

Re: gear oil??????

OK, my curiosity got the best of me and I just called 1800-TEAM-VAL... Valvolines toll free number. the guy there pulled up your Tranny specs, and said that yours calls for GL3... this you already knew. he then said that their GL5,4,3 fluid that you bought is good for "up to GL-5 rating" but that since your tranny calls for GL3, that you don't want the extra addatives that this fluid offers.. so he said take it back and get a specific GL3 fluid....... So that tells me they need to change their label and not say that is is SAFE for GL3-GL4 and GL5 applications... cause it isn't really......
