I have a 1994 F150 5.0 with 80K that I use periodically for chores, errands and towing a camper or boat. I am interested in knowing recommendations for oil viscosity for winter and then summer. I am not interested in going synthetic. I change the oil and filter every 3K miles and since I've passed the 75K mark, wondering what are the best brands and types to use given my driving/usage of the truck?

Thanks!

 

if its an older engine, get something with some good detergents in it. i use trop artic in my engines and it keeps them extremely clean. research some name brand manufactures and see what the detergent content is in them. good luck!

 

I would not change oil. Use the same thing you have been.

 

If it ain't broke, don't fix it.

 

what oil do you currently use? everything i drive i put valvoline max life its for higher mileage vehicles... since all my vehicles have over 100k miles on them..i have had great results.. but if what your using is working for you why are you wanting to change

 

I usually buy what seems to be the best deal as long as it is API aproved and and is in accordance to the Ford F150 manual's recommendations. I haven't tried the high mileage oils andwondering if they realy make a difference? I'm not going to switch to syn from dino at this point in the truck's life. So will likely keep doig what I'm doing using 5W30 year round unless I do some towing and I'll up the grade to 10W40.

Thats the thing to do right there. (although I use 20w50 for the fun I put em through.)
