In my Lexus IS300 I have been using bunch of oils and so far had great luck with 0w40 oils, all except for Castrol 0w40. But that's not the point. So summer came to North Carolina and temperatures of 65-85 started appearing. So I figured that I could go ahead and use up some Mobil1 10w40 High Mileage from my stash for the summer months. And guess what? Mobil 1 High Mileage 10w40 dissapeared on the dipstick faster than SRT 0w40, or Mobil1 0w40, or Castrol 0w40, or Redline 0w40, or even Pennzoil Euro 5w40. How is that possible?
I was always under the impression from this forum that the M1 HM 10w40 is the GO-TO oil if your engine has oil consumption issues. So how the heck did my engine consume it so freaking quick compared to much less viscous oils? I topped it off with some SRT 0w40. My usual consumption is 1qt per 3500-5000 miles. When I just started using SRT 0w40 - I had initial consumption of 1.5qt in 700 miles, but absolutely no consumption until the end of that 5k oci. And Now M1 HM 10w40 dropped level by a quart in just under a 1000 miles. Isn't it supposed to be one of the most consumption stopping oils ever made? Just wondering, thanks for replies, facts, and opinions. Love this community
