Equipment Make: Ford
Equipment Model: Ranger 4.0L V6
Oil Use Interval: 3,948
Makeup Oil: None
Oil Type: Napa (Valvoline) Synthetic 5w30
Miles on Unit: 46,209
Center column was a 3,791 run of Chevron Supreme and the far right column was a 4,000 mile run of Royal Purple 5w30. Used Napa Gold filter every change. Silicon actually went down this sample which is surprising since I installed a oiled cotton filter this time around! The fuel dilution in the current sample was probably due to some idle/low speed time just before the change. The grpIII from valvoline doesn’t look like it’s worth the price, the Chevron performed equally well and consistently. I have used Chevron since the truck was new other than occasional experiments with other brands. I’d like the lead and copper to come down, but I can live with these numbers

BlackStone Comments: We didn't find any change at all to wear for this sample, so though copper and lead are still higher than universal averages for the 4.0L Ford engine, we think they are normal for your particular engine. We did find a little bit of fuel dilution, which is common in engines that see a lot of city driving and/or idling. It has lowered the viscosity somewhat but otherwise doesn't seem to be hurting anything. We will keep an eye on it next time, as it should drop. Be sure to take the engine out on the highway prior to taking your sample to get rid of fuel. Check back.
