Well the good news is I've just paid for my truck, now I'd like to keep it running for a lot longer. What engine oil are u guys using? I have 60,000 miles on a 2003 sport ext cab 4.7.
I have been changing my oil and filter every 3,000 but on my last change I switched to a synthetic engine oil, at the same time changing the diff and transmission over to synthetic.
What do think? should I just switch back to non synthetic.
Cheers.

 

Mobile 1 5w20 Full synth only, Will never put anything else in her other than my ..... hours of loving maintance.

as for the other fluids, Ill only do synth.

 

this should be good

 

And FG says that because we ALL know there are a thousand plus one threads on this same subject and all have been beaten to death over and over.

What I use is all in my sig. Why would you NOT want to use Synth?

 

Goto the FAQ section, there is a rather large poll on this subject...

 

MOBIL 1 wherever it will go

 

I was going to switch the wifes Liberty to Synthetic but the Chrysler dealer only uses Kendall. He said he could get Mobile 1 but I didn't want to wait. Anybody have any feedback on Kendall? Also I see Lucas sells a synthetic. But I never hear anything about it either. They make a lot of other performance products. I have a 2008 4.7 Ram that I changed at 1100 mile and the next change I plan on going to Mobil 1 or Lucas if I can find out anything about it.
