I'm sure this has been asked before, but I can't seem to find it by searching.
I have been watching all the UOA's on the GC and would like to give this stuff a try. The only thing is, I live in Dallas, TX. It's pretty hot here in the summer and cold in the winter.
I am currently using M1 10w-30 in one car, and getting ready to run Auto-Rx in the other, and was going to run the M1 after the treatment.
I'm just scared of the "0w" part of this oil. How does this oil hold up in the heat? I noticed that the 40*C and 100*C viscosity’s are thicker than M1 10w-30, and I like that part! Also, the M1 is $1 cheaper than the GC...Is the Castrol worth the extra buck?
Thanks for all your help,
Brian Miller
