Had a previous thread going but figured I'd start another to get some opinions on the plan.
New Vehicle (31 miles) 16' F-350 Super Duty XLT 4x4 Super Cab 6.2l V8
Use: Daily Driver and Snow Plowing with HD Boss plow (my driveway and property...not commercially)
Type of Driving: mix of short trips with longer runs mixed (55mph 20 miles+/-) in...some very long runs 500+ miles
Climate: Extreme northern Mi. Very cold, very snowy winters, rural 2 lane 55mph roads
In looking at Fords oil spec for the truck it looks like most GL-5 5w30s are approved. Plan is dump factory fill at 1k, fill with Valvoline WB 5w30 and reset the iOLM. UOA with 5k on oil and every 2.5k after until OLM hits 5% if oil shows life. Filter will be Motorcraft 820s
I like the Valvoline WB conventional as it A. Meets Ford spec B. Is relatively inexpensive($14 per 5qt) and C. Is available everywhere. I've also had great luck running Valvoline Syntech 0w20 out to 15k in my previous vehicles. Since I'm just following the OLM in the truck though I see no reason to go syn.
I plan to have the truck for the long haul so the goal is to find a solid performing oil, generate a baseline of its useful life under my conditions and work within those limits.
I once ran a GM 4.3 to over 500,000 miles with out engine failure on Valvoline WB 10-30 changing every 4-5k...hope it still performers for me!
