This past weekend I purchased a 5-quart jug of Pennzoil Platinum 5w-30 at Walmart for $20.00 plus tax and a 5-quart jug of 5w-30 Valvoline Maxlife for $14.00 plus tax. Obviously that's a 30% price difference, but assuming that the oil gets changed every 3,000 miles or 3 months the difference translates to under $0.07 per day or $0.20 per 100 miles. Considering that most people on the forum run their OCIs significantly longer, why do so many people talk about one oil being a better value than another, especially when it's conventional vs. conventional. If you want to support the company with the best prices that one thing, but cost shouldn't be a factor in a choice that involves the oils quality. If you think one brand is better than another you'd be stupid to skimp over a nickel per day. Take a few minutes on the way out of work and find some change on the ground, problem solved!
