92ls forhundo Posted April 18, 2006 Share Posted April 18, 2006 I changed my diff. oil today and what significant difference it made, not major but significant in a subtle way, smoother acceleration, and just seemingly more tranquil ride.....good stuff....i recommend doing this, i know the heavy hitters do this already but for newbies like me it was eye opening.

Just out of curiosity, what's the mileage on your car, I plan to do mine soon as well. Quote Link to comment Share on other sites More sharing options...
mann777 Posted April 18, 2006 Share Posted April 18, 2006 I agree completely, i had just done after 138000 miles and now the transmission is so smoothe , guys go for it. It made a big difference in the ride . I happened to do it with the dealer himself at a fraction of the cost Quote Link to comment Share on other sites More sharing options...
92ls forhundo Posted April 18, 2006 Author Share Posted April 18, 2006 my car is about 245,000(my odo broke a year ago) it really made a difference in acceleration smoothness, also in stopping a "turbulence" from the drive wheels that i didnt realize was there until it was gone.

Ross W. Posted April 18, 2006 Share Posted April 18, 2006 I noticed that too when I had the diff oil replaced. Smoother and nicer. Make sure that the limited slip additive is included for cars so equipped. Quote Link to comment Share on other sites More sharing options...
SRK Posted April 19, 2006 Share Posted April 19, 2006 If you removed the same amount of oil that went back in new, there could be no discernible difference in the way the car drives. It's great that you feel better about the car - but there is nothing that new oil could do that older gear oil can't do in terms of driving smoothness. As far as I know, all Lexus with traction control have open differentials. If they had limited slip diffs, and the correct additives were not used, then there would be specific symptoms in driving that would be directly attributable to the clutches performance.

SKperformance Posted April 19, 2006 Share Posted April 19, 2006 I don't know of any LS ever to come with a locking diff. I used motul synthetic in mine and it felt the same after . Quote Link to comment Share on other sites More sharing options...
Shadow Posted April 19, 2006 Share Posted April 19, 2006 I changed differential oil four times on two different LS and not once did I noticed any difference afterward (I was pleased) which meant the old oils were working fine all along.

92ls forhundo Posted April 20, 2006 Author Share Posted April 20, 2006 well im not the original owner of this car so i cannot say how long that oil was in there but it didnt look good coming out....probably has lost some of its properties. Oh maybe im just crazy and there is no difference , that or i am just lying...... srk are implying that i dont know my car or that im so ignorent that i would fall for "the placebo" effect of changing my oil in diff? I greatly respect your opinions and enjoy very much reading you, however i cant stand being condescended to. Quote Link to comment Share on other sites More sharing options...

I greatly respect your opinions and enjoy very much reading you, however i cant stand being condescended to. I tried very hard to avoid sounding condescending or patronizing in my post. I think placebo effect is a bit strong, but at the same time I always think my cars run better after washing and vacuuming them out. After waxing my cars, I think they are faster, and I know fully well that it can't be true. It's all a part of why we enjoy them. I hope you understand my meaning here. What's truly important is that we work on our own cars, and that's always a good feeling - certainly more than saving money, it's the accomplishment itself.

92ls forhundo Posted April 20, 2006 Author Share Posted April 20, 2006 Srk, i completely agree, cars do always seem quicker with a fresh wash. My apologies. Quote Link to comment Share on other sites More sharing options...
SKperformance Posted April 20, 2006 Share Posted April 20, 2006 Actually a freshly waxed car is faster as it has a lower coefficient of drag from dirt and other contaminants. Just like you hand can grip on the paint and slide over it when waxed like silk ,so does air. Quote Link to comment Share on other sites More sharing options...
91LS400vgb Posted April 21, 2006 Share Posted April 21, 2006 I guess with today's fuel prices, it's only a matter of time before we'll see a wax company claim that their product will improve fuel economy due to a lower coefficient of drag.
