Synthetic junkie? Well, maybe a little. I have an '08 Chevy 2500HD pick-up and a '90 Corvette that both run M1 5w30. I run it in the truck because the oil life monitor will go past 6000 miles before it signals for an oil change. From what I had read around this forum the practical limit for dino oil in a gas engine is 4000 miles before the additive package starts to break down. Extended OCI's are nice too, lets face it. I run it in the 'vette, well, because its a 'vette. I've done some racing with it and am trying to squeeze a little extra power out of it, fuel economy, etc. I used to run Redline in it, but when that jumped from $8 to $9/quart, that was the end of that. I couldn't justify it any longer, switched to M1. I miss the Redline though, great stuff! Running wally world special (Supertech) 5w-20 in a high mileage '06 Accord, because I really don't care that much about it. All the lawn and garden equipment gets dino except for the new snow blower, the manual is calling for 5w30 synthetic but I haven't decide yet. I really only run synthetic where I can justify it. Which brings me back to the Kubbie. Its new to me and not sure how it is going to behave in cold temperatures, although you folks have helped to ease my troubled mind. The reason that I picked Rotella T5 is because that was the only 10w30 HDEO on the shelf at wally world when I went in, $16/gal. The price of the Amsoil 3000 series scared the heck out of me and made me question if 5w30 HDEO was really necessary in my climate. Its settled though, Kubbie gets T5 and no better. I may have the shakes for little while, but the fact that T5 is a synthetic blend will help with the synthetic withdrawls.
