I normally use Castrol Act evo SAE 20W-50 (premium Motorcycle Engine oil that I get from the local BMW dealer at around $6.00 per Qt.
Walking through Wally World (needed a new Timex dive watch) a little while ago I noticed their Castrol GTX High Mileage SAE 20W-50 and wondered if it really was the same thing? It cost $3.75 per Qt or it could be purchased in a 5 Qt container for $13.00.
Money is not the issue, just curious. Are they really the same or are there real differences?
