Well I did it!!! I bought all of the GC at the local AZ. The guy stocking the shelf thought I was nuts looking for the red writing as opposed to the yellow. Anyhow, my goofy Nissan only uses 3.5 qts with the filter so there isnt much elven-magic-juice in the motor. This little engine revs pretty good on the highway and as it is going through the gears. With the small amount of oil and high heat and rpm should I use a bit of LC in this oil? I know Terry has mentioned it but it seems like blaspheming. Should I leave the green stuff alone or spike it?
