5w-20 or 5w-30

[glock20man]

which oil is best, some factory manuals say 5w20 and 5w30.....?

I've used 5W-30 in all my Tauri up through the 2004 model year for many years without a problem.

It might also depend in what part of the country you're in.

I'm in MI.

I believe that from the factory, our cars want 5w-20. As the car ages, some people opt for a 5w-30.

so you get better mileage with 5w20 oil...? and now that winter is here should be easier start up with thinner oil "5w-20....? I used to use 10w-30 oil and I noticed ruffer idle.

I live in Montana and run 5-20 all winter and 10-30 in Summer which is 5,000 miles or 8 weeks in Montana !!! L@@L
Montana, 9 months of winter and 3 months of road construction~~~
Love the damn view!!! Just got some 5W-20 at the hardware store for $2.50 a qt!! Smelt like Valvoline so I went for it~~
I like good deals without Amazon or box stores~~

Someone gave me a free jug of 5w20, so I tried it. Worked good. I just changed it with 10w30 tonight, I usually buy 10w30.

[glock20man]

how about putting half 5w-20 in and the other half 5w-30 in when changing oil???

I just changed mine today. 1qt 5w20, and the rest 5w30. Reason?? I had one quart of 5w20, and a 5 qt jug of 5w30. I usually put in 5w20 only cause that's what Ford recommends.
