I have a 95 f150 and I usually run 10w-30 oil in it. I was thinking about running straigh 30 waight in it. Dose any one know if it would make a differance or not?

I can tell you from experience, whatever the sticker under the hood recommends for your particular engine, thats what you should continue to put in it.

------------------
1998 F150 xl reg. cab, 4.2L, 3.55
gear, auto, Lund tonneau bed cover, Pioneer CD receiver, EVERYTHING on the truck is black(including bumpers, grille, handles), aluminum wheels, K&N filter.

 

I started using 10W30 even though the manual calls for 5W30. It quieted the knock and it seems like the engine runs smoother. As far as going with the single weight - I wouldn't. The 10 of the 10W30 is there to get the oil flowing quickly during startup (at least that is my understanding - I am no expert in this area). This quickness is definately a good thing.

Whatever you decide - good luck!
