I have been using motorcraft 5w20 but some other guys I know are using Valvoline 10w30. I baffled at what oil is best. What are you guys using?

Mobil 1 5w20

 

Same here.....Mobil 1 products all the way.

 

I run Mobil One 90W140

 

 

mobil-1 oil and filter all the way.

 

What do you guys think about the K&N filter for our cars compared to the Mobil1?

 

Castrol Syntec 5w-20 and an FL820S Motorcraft filter

 

Extra Virgin First Cold Press Olive Oil.
Mobil1 5W-20.

 

Is safe to use any thicker than 5w20?

 

Yes, but only if 5W-20 is not available in your area. I would stick with the 5W-20! I am currently using Pennzoil Platinum 5W-20 in the Stang and German Castrol 0W-30 in the Crown Vic (4.6L 2V V8).

 

Why are you laughing? I'm dead serious I use 90W140 oil

 

please elaborate..! 90W140?

 

Hint: Original question did not ask exactly where in the car.

 

I bet he uses that in his rear end

 

Mobil 1 here too. I would not use anything thicker, like 5w-30. With tolerances so close in these motors it could cause damage overtime. Our mechanic at work was putting 10w-40 or 10w-30 in our V-10's. The first truck that was supposed to have 5w-20 in it started going thru a quart ever 500 miles.
