I was looking for places to buy redline for my next oil change. I noticed that the redline bottles do not say it is API certified.
My truck manual says that lubricants that do not have both the engine oil certification mark and the correct sae viscosity should not be used.
This is confusing to me. It seems that people here on the forum really recommend redline oil but it doesn't seem to meet the manuals requirement.
Please help me understand this.
