I can get Mobil One Extra fully synthetic at the local wally world here for $26 5quart container. But it is 5W30. Anything wrong with using 5W30 instead of 5W20. I live in the Midwest too.


Thanks

I switched between 5w20 to 5w30 and back to 5w20 again and never noticed any kinda difference with the way the car ran.. I think they say it's better to use a heavier when it's hot? or did I get that backwards? lol

 

I do the same thing csledd

 

I want to use the 5W30 year around if I can. I realize that you can switch between the weights, but if I choose this route(it is the cheapest) I want to use it year around. Am I going to get into trouble in the winter with the heavier weight oil?

You should be fine. The oil that they suggested for my Cobra (stock weight) was 5w30, and I switched to 5w20. I wouldnt worry too much.

 

Aren't people suppose to switch to a different oil after the car has over 50k miles? My pony has 79k and maybe its time to switch oil..

 

your car will be perfectly fine with no difference in results...
i ran that untill i switched to amsoil.

 

Part of the reason Ford and some others went to a 20 weight oil was because of gas mileage and tighter tolerances with the piston rings and couple other components. I run 5w30 mobil 1 year round. Not to mention it gets run hard at times. If you were running a petroleum product I probably would stick with 20 weight. Synthetic has superior flow capability over conventional at extreme temperatures. Should be fine.

 

Thanks guys, that is what I wanted to know.
