DMAXMAVERICK (AND /OR OTHERS)--I just purchased Mobil-1 75W-90--it might have a modifier added. Will this be OK for the G80 locker or should I return it? The product sheet states it exceeds requirements for ALL car and truck rear axles, and reduces chatter in limited slips. It states it is suitable for all applications requiring API service GL-5. Please respond. Thank you.
