quote:Many OEMs recommend oils that are too thin to be compatible with the quality of life for our engines. As you may well know, the OEMs key their maintenance requirements to the expected life of the car which will vary from 70 to 150K. Now, no one believes that the car will fall apart @ 70K but that is the point where one can expect to begin anticipating repairs. 0W20 and 5W20 oils just don't work when one is going to keep a vehicle for 10-15 years. There's no secret about this. A 20W oil is a 20W oil and by definition provides less protection than a 30W oil given that both oils are in functional condition. When SynLube provides a 1-2% advantage in gas mileage over the thin oils in addition to providing superior engine performance, give me a reason (Hint: There isn't one.) why anyone would use anything else, especially since it doesn't have to be changed but once every 150K miles.
Why use a 50w oil rather than as recommeded by manual, unless used in applications where oil temperature will be higher?
quote:Why not? PTFE does its part for the engine protection and is particularly effective protecting sleeve bearings. As I've pointed out exhaustively, properly implemented, PTFE helps an engine.
Why add PTFE if only for noise reduction?
quote:Yes!! It is better than any oil in any climate for any engine (except a rotary) on weekdays, holidays, Sundays, Boxing Days, and National Cement Pavers Day. No exceptions!!!!
Is Synlube any better than any other longlife oil?
quote:Since SynLube has been designed from the start to effectively fight soot, and other forms of contamination, one isn't taking any chance at all using SynLube for the full duration of its service life. Its ability to prevent deterioration in the first place is due to its unsurpassed ring-sealing ability. Many of the problems experienced with oils are a direct result of their reaction to the presence of heat, which causes oil molecules to bind to contaminants thus undermining the oil's ability to protect. Because SynLube's components are inert, deterioration of the lubricant occurs at an extremely slow rate. At the end of the service life of SynLube, it is still more effective than any other oil when new! Additionally, when it's time to replenish oil that's been consumed, SERVICE FILL or ADD OIL are designed to supplement the original additive package, not just replace lost volume. This is a fundamental difference from any other oil on the market I'm aware of.
With top quality synthetics the reason for changes appears now more to do with additives being used up not viscosity breakdown, mineral oil not even being used as a carrier. Soot/fuel dilution also change viscosity.
There is no reason not to use SynLube in a properly functioning engine. None!!!
It still amazes me to see people on board like this that are always looking for the best oil immediately scramble to find some excuse not to use SynLube.
I eagerly await the cries of denial that will follow this post. I love the ones about PTFE. I just have to laugh sometimes.
