i agree. 20W-50 =

the areas that mobil 1 usually win in in oil analyses is freed up horsepower. mobil 1 is usually very non-parasitic and puts more hp to the ground than most other oils. they do this generally by being so thin. if you got mobil 1 oil analyzed a few times, you'd probably stop using it on your own from the reports i've seen. mobil 1 is not bad oil, but it is definitely overmarketed and much of the praise is hype. people buy mobil 1 because it's the most heavily advertised, not because it's the best oil. people assume because it has the "mobil" name, it's good. well, it's alright stuff, but there's much better out there.

Also, I just switched from mobil one (for the above reason and others) to the GC 0w30, and I noticed a decrease in valvetrain noise. So for me, this has actually helped.

I do agree that Mobil1 is over marketed but I also feel that every oil has its own draw backs you just have to decide what draw backs you are willing to live with.

Not flaming just questioning

1.) it's marketed the best so the ignorant people (aka almost everyone) think it's the best.

2.) since it's the biggest synthetic oil out there, they can get it in huge bulk stocks for very low cost.

lol you honestly think the dealers - any dealer - puts the best oil in their cars stock do you seriously think they do oil analyses before they pick the oil? they just put whatever they can get the cheapest and has the best image. GM recommends mobil 1 5W-30 for corvettes. do an oil analysis with 5W-30 in a corvette motor. it gives poor, poor protection. please, use mobil 1 and send the results away to a company to be analyzed, then switch to GC 0W-30 and do the same. you'll likely get ~double the wear with mobil 1.

If you are using the correct oil and something goes wrong and its under warrenty (keep in mind GM now has the 100k mile warrenty or whatever) then GM will have to give you a new motor so it would be costing them money and not the customer. Last I checked you don't make money by replacing parts left and right for free..

I too feel that it's too much work to go hunting for GC 0W30. I'll be sticking with the M1 0W40 from now on.

that being said, i've heard of good results with their 5W-40 oil. however, since GC 0W-30 has put out the best test results i've seen and costs $3/quart less than amsoil, i see no need to buy amsoil.
