After my previous UOA I decided to drop my intervals to Ford's 5000 mile reccomendation for this car, rather than LC's 10K reccomendation. I did this based on my belief that the engine is not 100% right... it seems to be thinning its oil out, and unreasonably so, pointing to gasoline dilution of the crankcase oil. Due to a visit from the mother-in-law and weather conditions and my desire to not let anyone else do my changes, I ran 818 miles over my intended interval. The left-most analysis posted below was my most recent 5818 mile run with Exxon Superflo SM 5W20 and Lube Control installed at oil change and then 1 oz per 500 miles. Take a look at my below results and let me know what you think! The car is a 2002 Mercury Sable LS Premium with the 3.0 Liter 24V Duratec V6. Do not confuse that with the Vulcan engine of the same size available in this model. Usage was 60/40 highway-city driving. Oil analysis by Schaeffer’s Manufacturing. My car is currently running the second half of my case of Exxon Superflo 5W20 SM. I installed LC at 2 OZ per quart at install and am using a treat rate of 2 OZ per 1000 miles. Looks like all 3 fills of this particular Superflo were dramatically different formulas.

Yeah, I know what you mean. Still, $15 with shipping included beats $20 without shipping included. I feel like maybe I should get one Dyson deluxe analysis for a baseline once a year, and maybe do the Schaeffers at every OCI, just to get an alarm warning in case something goes sideways bad enough that the Schaeffers testing notices it.

That's that TomJones76 guy screwing up the columns. I used Kendall 5W30, then Pennz 5W20. My car's had 5W20 for every fill during my ownership of it except for that Kendall. With gas prices like they are, it seems like the sane way to do things, although I realize the annual savings probably won't pay for a single dinner at Olive Garden for me and the wife. With a 13 mile drive to work, I KNOW the thing spends most of its time well above the intended working viscosity of the oil. If it wasn't for my 110 mile round trips to my mother-in-law every couple of weeks, I'd be tempted to put some Rotella T SAE 10 WT in there. [Except the diesel-style add pack would still worry me re: my cat.]

Wear looked fine on the 10K run to me. 2.3 ppm/1K miles on iron, lead wear nil. Vis a bit low but hey...there's always 5w30.
