oil weight

[07Burb]

I guess there are no walmarts in Ohio, 5 Qt. jug of most brands of conventional oil are about 12 bucks. Your local auto store must love you.

really???? I need to start shopping at Walmart for my oil if that is the case!

Yep that is for basic synthetic. High mileage synthetic adds another $.50 a quart

In the winter I use either 5w-30 or 0w-20, depending on my budget. Living in Alaska, the difference between 0w and 5w is pretty impressive at -40 at startup, 0w gets around in seconds while 5w takes up to 20 seconds.

In the summer, when I used to live in Eastern Washington, I would put 10w-40 or even 20w-50, depending on how hot it would get. Here in Fairbanks I'll prolly just stick with 10w-40 in the summer.

And I can go 6,000 miles on a change of Valvoline high mileage blend and a Wix filter from NAPA. Right now with 5,500 miles on the oil, having driven through winter on this oil, it still has color and the truck runs great.

I would think with yours, in the shape it's in, I would stick with 10w in the summer and 5w in the winter and change it when it gets close to black.

for your mileage i would use a 10-30 10-40 as long as your not in a really cold area all of the time. for anyone with 150 or less you should use what is recommended in the owners manual. the higher weight oil you use the heavier it is when you cold start the motor which makes it harder to properly circulate. like the guy running 20/50 LOL unless you live in an area where its 110+ all year round i wouldn't even consider such a high weight. thats why he developed an ugly lifter noise

been using 10w30 since I have had the truck for the last 2 years at 246k miles now and it doesn't use a drop between changes, not sure if this engine was ever rebuilt tho
