Jeg er delvis enig i det du skriver Bie. Det er riktig at bilene fra fabrikk blir levert med en olje med pre-blandet LS-tilsetning i, og det hevdes at G80-lockeren fungerer best med slik olje.
Det jeg ikke er enig i er at G80 må ha LS-tilsetning. Både GM og Eaton skriver at de ikke trenger LS, kun ren GL5 olje.
Legg også merke til at oljen GM anbefaler mot clutch chattering (P/N 10950849) ikke inneholder LS-tilsetning.

Dette er typisk for alle diskusjoner om olje egentlig. Mange har sin mening om hva som er best og det finnes erfaringer som peker i alle retninger. Merkelig at det ikke skal gå an å få et fasitsvar på det her. Folk får vurdere selv egentlig etter infoen de vurderer som mest troverdig.
Selv brukte jeg Castrol syntetisk 75-140 GL5 olje på min Suburban uten problemer.
From EATON:
The axle is filled at the factory with a synthetic 75w90 GL5 rating made by Texaco under part # 2276. The GM service # is 12378261. This is the only lube we have done extensive testing with to insure locker compatibility. The only negative to using one of these other lubes is an increased potential for clutch chatter. This really doesn't hurt anything and can be corrected by changing the lube.

SUBJECT: LOCKING DIFFERENTIAL (G80) LUBRICANT - (SERVICE INFORMATION)
VEHICLES AFFECTED: ALL LIGHT TRUCKS EQUIPPED WITH G80 REAR AXLE ALL YEARS
Some light duty trucks equipped with locking rear axles (G80) may exhibit rear axle chatter, especially when turning a corner from a stop.
This condition of alternate engagement and disengagement of clutches in differential assembly is usually caused by contaminated axle lubricant.
To correct this condition, drain and refill the rear axle with SAE 80W-90 GL5 (P/N 10950849).
The use of any additive in locking rear axles (G80) is not recommended. Rear axle additives are designed for use in limited slip differentials which are normally installed in cars. All light duty trucks equipped with RPO G80 make use of a locking differential and the use of additives will delay the engagement of the locking mechanism and may decrease axle life.
