Just as Important as the oil they use is also the oil filter they use. Most quickie places and Walmart use the Orange filter you know sounds like Tram.
Well I researched this subject many times and there Isn't much filtering going on with this make of filter. I have the sites marked on my other PC but I will never use that orange filter. You may as well use toilet paper. I still live up north and perhaps once a year I use the quickie places. I bring my own filter and my own oil and I watch to make sure they do use my oil.
Buyer Beware.
