    Hey gang
    Just got off the phone with WCD and they claim that the Sta-Lube brand is BAD gear oil and will "Burn up a R&P"!!
    Has anyone ever heard of this?? They absolutly hate Sta-Lube and swear it will ruin my gears??!!

    Ok so let say I trust thier judgement and run out at lunch and buy new gear oil, what brand should I get???

    What do you all think about this????

    I personally love Valvoline products. I highly recomend the dura-blend 80W90... Once I get my beefed up 12b redone I'll run full synthetic cause the pinion is aimed up pretty good for the CV shaft, but that is a spendy price if you hit water... about $10 a qt compared to the regular @ $3/qt and Dura-blend @ $5/qt.

    I mostly just use Valvoline gear oil in in all my vehicles. It has caused me no problems. And everything always looks ok when I pull the covers. Also I have never blown a rear end.
    But I do use Stay -Lube gear oil in my boats outdrive. Because I refuse to pay the outraious price Merceury wants for their lube. I think that a marine outdrive is in a far harsher environment than a rear end in a vehicle. Stay lube has worked ok for it. the boat is an 85 and I have not had any outdrive troubles. but I change the lube often in all my stuff. Maby thats the secret to a long and happy life.

    Ya know I asked WCD about synthetic gear oil too and they said it is not recomended for Limited-Slip diffs cuz sythetic removes friction and LS diffs work off/with friction. So.......
    Ahh hells bells, I would think that oil is oil and as long as it is changed regularly then all oil is good enough.................................................???????????????????????????????????????

    Thanks Thunder! That is exsactly what I was thinking. As long as you change it regularly then all should be fine.
    WCD got me all spooked into thinking I am gonna blow a R&P cuz of the gear oil I chose.
    Anyone else had good or bad to say about Sta-Lube???????
    I know it's not the 'best' oil on the market, but does that mean it's 'BAD"????

    stay-lube oil is a very cheep brand of oil. stay away from it. I had used it a few years ago when I had changed gears and put in a limited slip. With in 200 miles the cluches started slipping and started making noises. I had asked a machanic what was going on, so I told him what kind of oil I was using, so he said use a good brand of oil. I went to what GM uses and it was fine after that. I was told Stay- lube breaks down to fast under that kind of heat. Hope this helps

    I"am just about ready to break in a new set of gears front and rear. Stay away from synthetic oil for the break in period. I"ll use GM 80-90W for the first 500 miles, then I will use Red Line 75-140W synthetic. Synthetic oil dissipates the heat so much better. Just stay with a good brand of oil.

    I'll tell you what, I probably have 2 gallons of sta-lube in my truck, 80-90W. Front and rear diffs (10 bolts with gov-lock in back) SM465, and the NP205. Nothing in any of those components is new. All unknown usage, but at east all are 15 years old. Had the oil in the truck for about a year, and haven't had any problems.

    If I was setting up a new ring and pinion, I might go for a "better" gear oil, just for some peace of mind. Just remember though, the ONLY people that really know how good ANY given lubricant is, are the chemists that designed and tested that lubricant.

    Just like not letting anyone work on my truck because I don't trust their skill, I would probably make my own lubricant if I could!

    One complaint I do have, of all the gear lubes out there, NONE of them I have seen so far, actually say whether or not you need to add GM limited slip diff lube or not. They have meaningless "meets GM spec XXXXXX", butI don't know about anyone else, but I have no clue what GM Spec# I need.

    I typically run with Mystik - if it's good enough for heavy trucks, it's perfectly acceptable for my Blazer. I've also run Sta-Lube in just about everything with no problems too. I'd go with a more expensive oil on anything new and/or anything seeing extreme usage.

    If it weren't for bad luck, I'd have no luck at all[​IMG]

    Hmm... no synthetic in a posi... I don't think that is right... considering all the New GM's come w/ synthetic diff fluid... even the posi's. I have heard of problems w/ cheaper lubricants used w/ posi's, but usually and extra bit of posi addative solves the problem.

    I really tend to frown on the people who go w/ the cheapie brand crap... a good rule of thumb to follow is "You get what you pay for". 9 times outta 10 it is the truth. I think it is especially true w/ oil... because remeber oil breaks down.... so why go to the work of changing the oil 3 times as often cause it breaks down faster just to save a $1 a bottle? Just my $.02

    I just want to kill off a gallon of Sta-Lube so I can refill the jug with Valvoline Durablend and use their nice handpump!! Beats the hell out of rubber tubing on the end of the Valvoline bottles for my front axle...


    If at first you don't succeed, failure may be your style...
