Yup. I think I may have been going too long on my oil.
I bought a new 2011 F150 with the 5.0 last July (love it BTW).
I've been changing the oil every 10K miles using 5w20 Valvoline White Bottle and a Wix filter. But my 10K miles involved a LOT of idling ALL DAY for 6 days a week (100+ degrees out and I need to be in my truck with the AC on) and a lot of off-road driving and I tend to hit the governor at least once a day on the highway and generally cruise at around 80-85 mph.
Aaaand on top of that, during each OCI, I've needed to add a quart of oil at around 7K miles. So for the past two OCIs I topped it off with Lucas Synthetic Oil additive (it's expensive so it must bee good right?) The first two times I topped it off I used 5w20 VWB.
On a positive note, I've never towed/hauled anything with the truck and I very rarely floor it. I almost always manage to keep it under 3K RPM.
It now has almost 50K miles on it and I'm almost due for another oil change.
For some reason I stumbled on this site and got to reading and now I'm all nervous about my motor/oil.
I already have another 8 quarts of regular 5w20 Valvoline and a Wix filter purchased.
What does the hive think about what I've been doing, and what should I do next?
