Also, I recently (last week) made the switch from Rotella to Long-Life in a friends old Ford gasoline engine tractor. It was using the latest, greatest CI-4/SL Rotella, but after putting the new Long-Life formula in, consumption has dropped a GREAT deal! Once again, I must say, that in my actual use, Rotella and Long-Life are not the same formulation!

quote:No, I haven't tried Auto-RX. Yes, the Long-Life is working quite well, but I definitely have caught the oil "bug"! My "reasoning" for thinking about changing is simply because now that the engine is internally clean, I'm seriously considering switching over to a PCMO (shhhh..don't tell anyone!) in hopes of reducing blue smoke on startup. If I could find an oil that would keep consumption low while improving startup smoke, then I'd be set! Wonder if I should give the high mileage oils (and their reported seal conditioning agents) a chance???
