Well that's encouraging. Seems like everyone thinks it's o.k. As for the possibility of it being recycled oil, I don't think so. I checked the package carefully and can't find anything stating that it was other than new oil.
Regardless of the type of oil I use in my vehicles, I just can't seem to feel good about running them longer than about 3500 miles on an oil change. That included a little Dodge Neon we had that I used only Mobil 1 in. So an oil that needs a shorter drain interval probably is the best choice for me. I did spend an extra dollar to get a filter with better filtration and drainback valve, so I'm not a total cheapskate. /forums/images/graemlins/smile.gif
I still use Mobil 1 for really demanding tasks. For example, I have a 4-stroke outboard (Merc 40 efi) that is specced to run 6k on the tach wide open. I use Mobil 1 in it and am very glad I had it the other day. My thermostat stuck closed due to a lot of debris in the water and the motor got quite hot . . . 195 on my temp gauge. It normally runs 145 max. Having no other choice, I limped back to the ramp at idle, shutting down periodically as the alarm sounded and the temp spiked over 200. I made it, but was very concerned. I actually had to pull the thermostat, as backflushing didn't help. I also drained the oil, which was VERY dark, unlike the last change where it came out looking like it did when I put it in.
The motor runs fine now. I'm pretty sure had it been a two stroke that the ending wouldn't have been so happy. I'm also pretty sure that the Mobil 1 saved my butt that day.
I also use Mobil 1 in a small Honda water pump I use a LOT. I think it only holds 3.6 oz, so it's not a big deal either way. /forums/images/graemlins/smile.gif
