I know you are supposed to use 90w, but all we could find was 85w-140. Is that ok?! The other option was 80-90 and we thought that would be too low. Thanks! | ||

actually its 80w90, according to D1 owners manual. If you worried about it been too thin, add Lucas stabilizer (which is good idea anyway). | ||

Also just remember; Education and Entertainment cost. Your education from here is real cheap. All who use it for education should pay something, and those who use it for entertainment should contribute too. Just for the short time I have been a member; I have had great education and entertainment. | ||

yeah, I was thinking the same thing!!!  Can we just talk about OIL?! | ||

Susannah, the oil you suggest should work fine. I presume you are looking at a synthetic oil? | ||

Education?: 80W90 for standard driving...the 85W140 is for long "hot" highway miles pulling a trailer and really working the gears Peace. | ||

I use 85w 140 in mine here in Ozzie. Seems to run fine Bazzle | ||
| Justin V. Nevitt (What_rd) New Member Username: What_rd Post Number: 17 Registered: 02-2004 |
Running either oil will work fine in average situations and the occasional higher stress situation. But, the 85W140 performs better in the harsher conditions than the 80W90. Word. | ||

Hmmm, now we are a bit confused. I guess we will use the 80w90 for now. It's for both the RRC and the Disco. Both aren't driven very much...Disco more than the RR. What about the suggested time interval between changing out the oil? | ||

I use a synthetic 80W90 and have been very pleased with the results. | ||
| Ron Brown (Ron) Senior Member Username: Ron Post Number: 806 Registered: 04-2001 |
They both work fine. 80w 90 is recommended, 75w 90 synthetic for D2 Change at 30k or whenever you have water in there (check after wading etc.) Ron | ||

I need to change the fluid in my diffs and transfer case in my D2, but have not been able to find 75w90 except for the limited slip stuff. Can I use 80w90 instead? Mike | ||
| Justin V. Nevitt (What_rd) New Member Username: What_rd Post Number: 22 Registered: 02-2004 |
Yes, just change it like Ron suggests. Peace. | ||

If I remember correctly, 75W90 is thicker to begin with compared with 80W90, and then thins to 90 weight. Is the difference between these two really make a difference? | ||
| Justin V. Nevitt (What_rd) New Member Username: What_rd Post Number: 24 Registered: 02-2004 |
Where did you hear that? Even if it were true, what the hell would it matter? How many people actually put 400K miles on one truck? Change the oil like you're supposed to, and it will last until you are ready to sell it. Think about it. Why complicate? | ||
| Porter Mann (Porter) Member Username: Porter Post Number: 149 Registered: 05-2003 |
Its not about complicating the issue but finding out the various ways to do the right thing. The question is, can X do the same thing as Y, even if the bottle has something else different on it. This board is about sweating the details and getting down to the nitty gritty about things. We're really are asking "what the hell WOULD it matter". | ||

nope...starts thinner in cold conditions...hence the first number is lower....protects to the level of "shear" of the high rated number equivelent Dino. so 80w 140 will have the flow characteristics of a 80 straight weight gear oil but still protect to the shear level of a straight weight 140 gear oil. SSV....use the 80w90 and you'll be fine...a addition of 25% lucas stabilizer will also help you if you let your truck sit for a long time because it will keep more lube on the un-submerged gear teeth while it sits and prevent rust.

Porter, How different could they really be? They all do the same thing. 80W90 - standard gear oil 75W90 - synthetic = more money, same thing, what's the point? 80W140 - thicker for hotter operating conditions(and I don't mean ambient temperature), use if the paint is melting off the diff housing @ the ring gear bulge. Is that nitty gritty enough? Later. | ||

i use 90w140 synthetic oil in the differentials. I ve been using it for over 2 years now and no complaints. its red line. I carry heavy loads and drive up and down the baja and mainland mex both on and off road. provides a lot of protection in hot weather with heavy loads. |
