I saw good old bob once and the test he did. This IMO is NOT real world or life of a motor. Do I run additives in my fleet, YES. It started about 36 years ago with just STP. I have 2 motors with over 120,000 miles on them. Racing hard drive, high speed driving. These 2 motors always have good
oil pressure when hot or cold. I like the fact of having a clinging
oil in my motor. I am more than happy to give up a couple of HP and extend the life of any motor. I broke a rocker shaft when racing, this was before I added my accusump to the car. I ran the road course at Gateway. Lifter poped out of the bore dueing the run. 1.35 miles. I finished the run with 20 psi of pressure. I pulled the 452 bottom end and found no damage other than a couple of small scratch marks from the motor running low
oil pressure. I think that the clinging oil helped save the bottom end bearings. I now run an accusump as a peroiler for the motor before startup and when running long "g" turns that cause oil starvation. This keeps up the oil pressure until the pickup is submerged. 70-80% of wear on a motor is done dueing startup when the oil has only the oil left on the parts after it drain off from running.
I have run the cobra motor to 6,000 rpms racing, I have not seen ANY FOAMING ISSUES with Lucas or EOS. Maybe at 7,500 rpms this my happen. Lusac cost $8.88 in Pepboys for the next 2 weeks. I have picked up 6 bottles.
This issue is about choice and what you believe. I am not buying Bobs test. I have done my own with my cars and trucks. Quiet cold starts an no motor noise is my ONLY concern. You can make any fluid foam if compressed and whipped enough at a high speed. This is the main reason I don't like Mobil 1 oils. Too thin and it just run off the bearings and surfaces when sitting for a couple of days. Have done this test with Vettes at work. Bob's test may also be questionable with how he mixed the suppliment and oil together?? I would like to hear the answer to this question. Rick L. Ps I don't have any stocks in the oil companies, Lucas, or a PHD. Just common sense.
