Hi all... It's been a while since I have frequented this board and this question most likely HAS been answered
in the past.. but here it is.. Is there going to be any problem (oil consumption / leaks) if I change to a
synthetic oil like Mobile1 now that I have over 135,000 on my 94' 2500 suburban (454cid). I have been towing
my 31' Airstream around thinking that a synthetic oil would give me much better protection in the event things
got a tad bit overheated under the hood. Any comments about changing at this late date / mileage?
Thanks for the help.
