Jon.
My mistake. I thought I had read a post where you use a closed system?
Does your motor have the oilfilter in it's original location? Many do not know a Ford 302 only filters 1/2 the oil pumped which if oil stays changed is not really a big deal especially with cold starts.
I have another friend that uses his 1989 Ford F150 for home A/C repair business. He also is a straight 30 wt Pennzoil user thet I have tried to get to use a multi wt because it gets pretty darn cold here in the winters but he is a diehard and really he has had success running this oil as well,,275 k and one timing chain. I certainly can't say that's a bad report on a oil or engine design
That sludge rumor from the use of Pennzoil is unjustified in my opinion. A dino oil can only be run so long anyway any of them before a oil change is needed,,town driving with short trips,water pump goes out and over heats motor badly is not some of the things taken into consideration when a mechanic or machine shop makes their statements. If you would,please take a look at my topic"funny how one guy can give a oil a bad reputation" or close to that name
Edited to ad,I think if you were to use the Pennzoil 10/40 you would get all the protection and cleaning abilty you would ever need for your ski boat or any other high quality OTC oil.Yep, the Valvoline is good as well but the cracked Pennzoil is a great oil and so is Chevron,Motorcraft ect.
