Just thought I'd up date this. From a driver prospective I cannot tell the difference between 10W30, with 1/2 quart of hyperlube vs 15W40 Rotella. Blue puff at start up seems about the same, oil use seems about the same, possibly slightly higher, but that would be the valve guides. What will I do at the next change? Not sure I'll prob stick with the 15W40 for now at least.I didn't want to post this in the main post, but I'd like to add this. On my personal truck I've been running regular conventional Valvoline 10W30, plus substituting a 1/2 quart with hyper-lube stabilizer. The reason being is that I run the truck pretty hard from time to time either loaded heavy or with the trailer, I figured it could use the extra protection of the stickiness. I've had pretty good luck on other vehicles with hyper-lube reducing oil leaks and smoking so I felt comfortable using. I run it in my Jeep which has lifter noise on start up and with the hyper-lube it doesn't do that. however in my research I learned hyper-lube stabilizer and the Lucas version are essentially just a thick sticky base stock without many if any additives. Fine for what it is I guess, but if you pour it in your engine you are thinning the other additives out. So in my example the 800PPM zinc in my motor oil might be closer to 700PPM after I've subbed out some of the oil with hyper-lube. My engine is stock and I change the oil every 3K, but I've decided to try diesel oil. I picked up a 2.5 gallon jug of Rotella and change the oil this morning. I do get a little puff of blue at start up do to worn valve stem seals, the hyper-lube did not seem to help that much if at all, so I'll be curious to see if the diesel oil changes it at all. 200 mile feed run tomorrow so I'll let you all know if I notice anything.
