With 50K on engine rebuild, it was time for another rebuild. Using 2 qts of oil daily in 85 miles. Rob the mover, diesel driver gave me a gallon of Lucas. Put it in the Suburban, about 50%. But it’s too cold outside Rob (I said) “Put it in”, So I did and in a few days stopped using oil, to a qt. every 3 wks of driving, and that was 4 yrs ago. I've since sold the suburban and its still running on Lucas 60K later. THANKS LUCAS
