WJM Posted October 4, 2003 Share Posted October 4, 2003 Ok, I am debating this...now its itme to debabte this here! What would happen if I used 10w-30 or 15w-50 mobil 1 fully synthetic motor oil in one of my 5spd transmissions...?? Ive got an XT turbo 2wd 5spd, an XT6 FT4WD 5spd, and the 87+ RX 5spd D/R.

toybuilder Posted October 4, 2003 Share Posted October 4, 2003 I believe that your transmission will die a certain death. It won't stick to the gears well enough to properly lubricate everything inside the transmission. Quote Link to comment Share on other sites More sharing options...
TomRhere Posted October 4, 2003 Share Posted October 4, 2003 Other than maybe more noticable gear noise from the tranny, only other thing I can think of would be seal problems. Most seals are made to work in a particular type of fluid. Subjecting them to another type of fluid, for extended periods, may cause them to swell, or deteriorate Used to be all trannies, and tranfercases were 80, or 90 gear lube. Then alot went to either 5W30 or 10W30. Now, alot have ATF in them. Not much other than the seals have changed, from what I can tell. Maybe a slight different cut on the gears to reduce gear whine. Never know untill some one tries something, if it will work or not........ Quote Link to comment Share on other sites More sharing options...
WJM Posted October 5, 2003 Author Share Posted October 5, 2003 i guess i'll try it in my GL-10's 2wd 5speed, since it will be comming out soon anyways. Quote Link to comment Share on other sites More sharing options...
DerFahrer Posted October 5, 2003 Share Posted October 5, 2003 The only cars that I know of that take motor oil in their trannies are Hondas :eh: Quote Link to comment Share on other sites More sharing options...
Setright Posted October 5, 2003 Share Posted October 5, 2003 WJM...why??? Go for Mobil 1 TRANSMISSION oil, or Redline NS oil Quote Link to comment Share on other sites More sharing options...
WJM Posted October 5, 2003 Author Share Posted October 5, 2003 for experimentation's sake. the NAPA I work for does not offer Redline, or Mobil gear oils....and i dont even know if we can get AMSOIL easily. Quote Link to comment Share on other sites More sharing options...
Meeky Moose Posted October 5, 2003 Share Posted October 5, 2003 sorry gotta say this, my cousin worked at a napa in colorado, said NAPA stands for "Not Any Parts Available" anways... if i were gonan experiment i wouldn't go anything lower than 20W50.. my friends acura 5-speed used straight 30W and it imploded at 120k and he's an old fart so he doesn't hot rod it either.. just my .02 Quote Link to comment Share on other sites More sharing options...
