First things first......the engine oil and transmission oil looked about the same, both a greyish color. To clean those up I have a two step plan.......
The first step has been implemented and consisted of the following:
- Change engine oil with Valvoline MaxLife 5w20
- Add Rislone engine treatment with new oil
- Change engine oil filter
- Drain transmission pan and refill with Valvoline MaxLife ATF
- Change engine air filter
- Add BG Products CF5 fuel treatment in gas tank
My plan is to run this for between 500-1000 miles allowing the Rislone to fully circulate and trap any gunk in the oil filter. Right now I have about ~600 miles on her since this work was completed so may do step 2 next weekend or the weekend after depending on "new house chores".
I filled up with fuel shortly after doing step one and calculated 27.79mpg. Not bad to me considering my truck gets about 10mpg. But I knew she could do better due to reports from others that ~30mpg is attainable even in winter months. At the second fill up I calculated 29.91mpg which is the first full tank with the step one work completed. Much better! I think things are starting to clean up nicely on the inside
