I have 12 bottles of SLOB. Unfortunately have not been able to use it yet because I had to use up some older STP zddp stuff (not the thick crap). Anyway, then Bruce381 gave me some 21000 ppm zinc, etc. PCMO additive and I have to try that out for him. Sometime late this fall the SLOB should get a tryout. Meanwhile, I am waiting for the VOA of it as I just sent the sample in yesterday.
That's about where I'm at. The Aerostar is filled with Redline and halfway through it's OCI (approx 6000 miles and one year). Motorhome may rack the miles though if we take a trip soon and then I could SLOB it.
What type of oil are you gonna run w/ your SLOB? I had been planning to do a 15W40 HDEO for my next OCI but w/ SLOB that may be a little too high a viscosity!
Both those vehicles would run 10w30. The motorhome either Maxlife SL or Pennzoil Synthetic SL. The Aerostar will get Maxlife Synthetic which is 11.5 cSt. In either case the SLOB should be fine. I was inclined to half a bottle, but now think the whole bottle would be better for about 400 ppm boost.
I was thinking about it for spicing up my more mundane oils like my SuperTech 5W30s and 10W40s I don't have the specs on them, though...and given how they use so many different suppliers, I am not sure I could get them.
I am planning to try it with some Havoline dino 10W30 in my Jeep. I figure with the high Moly in the Havoline, and the add the heavy dose of Calcium, Phosphorus, and Zinc in SLOB, it may just create the perfect oil. Am hoping to do a before and after UOA to see what happens with it.
