Detroit Truetrac
Q: What kind of oil should I use? Can I use synthetic? Do I need friction additive/modifier?
A: A quality petroleum/mineral based oil works best in the Truetrac units. We do not recommend synthetic oil. Friction additive/modifier is not required.
Eaton Posi
Q: What kind of oil should I use? Can I use synthetics? Do I need a friction additive/modifier?
A: Eaton Posi units perform best when using GL4 (or better) mineral/petroleum based gear oil. A four ounce bottle of friction additive/modifier is also necessary for optimum performance.
Detroit Locker
Q: What kind of oil should I use? Can I use synthetic? Do I need friction additive/modifier?
A: A quality petroleum/mineral based oil works best in the Detroit Locker units. We do not recommend synthetic oil. Friction additive/modifier is not required. |
This is exactly what made me run dino oil with my tru-trac in the first place which ultimately lead to all of my gear failures. C&R was perplexed right along with me as to what was going on since everything other than the gears looked fine, no evidence of lack of lube or overheating, the metal was being displaced on the face of the gear teeth so I believe the dino oil simply couldn't tolerate the load being put to it.
