Hi all!!

The plenum is due on my 1994, but I want to do it on my vacation in a month....a friend told me if I ran 15W40 oil it would smoke less (I guess because it's so heavy it won't make it thru the plenum gasket?)

Any thoughts on this? Am I risking damage??

Thanx

 

Don't know about the "smoke less" LOL But you are fine running 15w-40.

 

I ran Rottella T 15w-40 last year. It was fine in the summer/fall but took too long for my liking to circulate in the winter. It would knock for about 5 or seconds till it got flowing.

 

loll..I'm french so the right words are not always at the right place LMAO!!

 

It's all about the same when its hot anyway

 

any oil is fine. just keep it full and fix it whenever you can.

 

If you live in the south, which you don't, then thicker oil is always a good idea. In the north, I use 10w40. 10w30 is too thin with as many miles I have, and like previously stated, 15w40 took too long to circulate in the winter. I'm loving MaxLife 10w40 for all-season oil with 155k on the clock. Just fix the plenum then worry about oil.

 

I know Ramman...but right now doing the plenum is not an option....

 

I use 15w40 always even in winter when it gets colder than 0f never had issues over 300k on my 96 ram my 98 is at 200k and even my girlfriends sunfire I put that in it

 

i heard it should even clean the engine out for you.
