It’s more like one brand of Phillips screwdriver can fit more than one brand of Phillips head screw. Using coolant instead is like the hammer to cut bread, you’re not that far away.I don't really get these all-in-one fluids. I don't try and use a hammer to cut bread even though you could theoretically do it. Use the right tool for the job.
Add in the fact Valvoline is owned by Aramco now, and I am out.
