1979 Mark V Oil Suggestions

Hi Bill,

I recently purchased a 1979 Mark V, do you recommend synthetic oil and at what weight..

Thanx,

John

Hello John -

Congrats on your Mark V purchase. If you have a nice Clean, Quiet engine in Good running order that uses (burns) not much or minimum oil between scheduled oil changes, a good brand of premium high detergent 10-30 motor oil for normal summer driving or 10-40 motor oil for high speed hot weather driving will be a good choice. Synthetic oil is even a better choice for a clean good running engine. Unfortunately, no brand or weight of any oil will repair worn out parts inside of any engine. This opinion is only my opinion though, many other opinions can be found all over the internet in automotive forums.

Sincerely,

Bill
