Best Engine Oil for 02 7.3L
just wanted to get some opinions on the best engine oil. i have been using mobil 1 synthetic 5w30, thanks for any comments
|
My vote is for Schaeffers 5w40 synthetic. I can get it for $12.75/gallon.
|
Shell Rotella T6 5W-40 Syn........
|
THE "U"!!! can u pick that up online cheaper or do u get it at a local shop, i was told that once you go syn. you have to stay with it
|
No......don't think so, but why go back, Rotella is an excellent oil. Do a google search and read on..you will see for yourself. Many places offer it including Walmart, well some Walmarts. Also if you have a Menards in your State, the oil is on sale.
|
why are you guys running 5w instead of 15w which is what the owners manual says? I don't know much about the diesel motor, just looking for some info. thanks for the responses beforehand!
|
Much thiner when it is cold. Such as here in Michigan it was 1.3 degrees F the other day. 15 is like tar and 5 is like honey at that tempature.
|
Easier starts in the winter time when its cold.............quicker lub at warm up.
|
is it ok to run 5w in the summer (ie 100 degrees F) ??
|
Mobil1 5W-30 isn't a good choice for your 7.3 IMO. The weight isn't ideal and neither are the additives. You want to stick with a 5W-40 diesel rated oil. I use the Rotella myself.
