Friends...in searching the 4G TL forum I haven't found any 4G owner perspective about this motor oil for our cars here on AZ. Is anyone using this oil and or brand of filter? I understand there are a lot of personal opinions about motor oil and I want yours if you have used Royal Purple? Everytime I walk the oil aisle at Wally World the purple 5 quart jug catches my eye however I've never used it. I do my own oil changes every 4-5K miles and I don't really concern myself too much with the cost of oil, I simply want to get the best oil to keep my motor clean, deposit free, running smooth and provide me with many many years of service.
