The last run I did in my Wife's car (02 Ford Taurus with 3.0 Vulcan) was a franken-mix of leftover stuff and 1 pint of Marvel Mystery Oil. I used a mix using the rest of the MMO and random 10w30 oil to top off over the course of the OCI.
It made it 4,800 miles and through a really cold winter (For Texas), before I realized that it was getting warmer out and I wanted to go ahead and change the oil out while it was cool outside and not 100+ degrees (not fun under a hot car and on top of hot concerete).
BTW, I had a SuperTech filter on there that I had to repeatedly tighten because it had a very slow leak around the gasket. I think I will spend the extra dollar and twenty cents and buy Motorcraft filters now.
Being that my stash is upwards of 40 quarts right now, much of it synthetic, and she drives more than I do I decided to fill it with Synthetic for the first time.
Typically I leave the Synth for the Xterra (small sump) and F-150 (1 year drains), but I actually get tired of putting the Taurus up on ramps because 5000 miles comes fast.
So in went the Quaker State 10w30 Torque power with 1 bottle of Schaeffers #132 Moly EP Oil Treatment and 5oz of LC20.
I plan on letting it be in there for 10,000 miles (LC20 says so
) and then sending some out for a UOA. A Motorcraft FL-400s went on also.
The Schaeffers #132 is very thick. It has a blue tint to it and reminds me of STP oil treatment, but I know it is made by a reputable company. The LC20 is VERY THIN, I think it will thin out the #132 some. I am really interested in how this brew holds up over the summer and into the fall. 10,000 miles shouldn't take too long to rack up.
