Hello, I'm just another 'oily newbie' so please accept my apology if I've posted this question in the wrong forum.
I have a brand new 2009 Ford E-350 XLT SuperDuty 12-passenger van with a 5.4 V8. The Ford recommended oil is 5W20.
My previous '99 van was the same model with same 5.4 engine, but the recommended oil was 5W30.
The '99 engine was great but sold it with 360k on the odo. 2 weeks after an oil change (approx 600 miles) the oil was still an orangey-honey color, transparent on the dipstick... Beginning to darken, but low enough carbon present so you could still see the cross-hatches on the dipstick clearly.
The 5W30 oil I was using combined with the frequency of change & new filter was obviously working fine. No, haven't done an oil analysis, didn't appear to be a need for it.
I have enough of the 5W30 oil still on the shelf in the shop to do roughly 20 oil changes. I would like to start using the 5W30 instead of 5W20 after the factory warranty on the truck has expired as long as using 5W30 doesn't bring harm.
Will the 5W30 be fine on this 09 5.4? Or are there critical differences between the new and old 5.4s to prevent me from using the 5W30?
Hopefully with your help... If I discover I cannot use the 5W30, I can try to sell it to someone who can use it rather than let it sit on the shelf in the shop until the truck warranty is up. Better to sell it sooner if it needs to go.
This is a great forum here! Lots of knowlege in the posts! And lots of reading and learning for me to do now!
