what oil do you run with your F134?

Hey everyone,

I'm in Virginia so we don't get too harsh of winters, and steamy hot summers. I've always run plain old 10w-30 in my jeeps, but I'm curious what everyone else runs in their F-heads? Is there any good reason to run a different grade oil at the climate I'm at?

Havoline 10-30 over here. I think that changning it often is more important than what grade/brand you run. In hot weather, 10-30 should be fine...I've switched to 5-30 in extreme winter weather, but it's not usually necessary.

 

I use Havoline 10-30 and put lucas oil treatment in.

I've always been a good example of a bad example but (not much comparison...BUT) My Diplomat had 100,000 miles exactly the day I bought it and changed the oil and used whatever filter and oil was on sale, Been changing the oil every 2 years or soo (when ever I feel like it) and have estimated that I put another 70,000 on it since. Oil pressure is at 14 psi at low hot gallop idle (light racing cam) I understand changing oil is a good thing but after 10 years and about maybe 4 or 5 oil changes with no problems in pressure, I figure "why change my way's?"

Also I might add that I also use "Restore" in place of every other monthly quart of oil it needs (due to leakage) .


I guess I like the idea of the old pickup's with 3 on the tree that you NEVER change oil or clean the engine but just add oil when it needs it and keep's running beyond 200,000 miles

 

Straight 30w in mine. Have considered going to straight 40w, which is what my '94 Malibu ski boat requires.

 

I need to figure out what type of oil I should be using in the middle of the summer here in Tucson when the temperatures can get up to 118° in the shade. I've been told that the heavier weight oils make the engines work much harder. So I will be asking everybody, because I want me F-134 to last a long time. If you have good oil pressure, what does the heavier weight oil actually do for the engine

in your case i would use 15w40,but if you have good oilpressure carry on with what you are using,here in VA i use 10w40 and change @ every 3000mi religiously but you have to take the conditions your particular vehicle is experiencing into conideration

 

10-30 (below 50 degrees) in winter and 10-40 in summer (Above 90 degrees).
