OK, I'm a woman and I think I just got the shaft. I brought my car in for an oil change at a "chain repair shop". He asked if I wanted to have a regular oil change or synthetic and asked how many miles I would drive before changing it again. I said, "I drive about 7,500 miles. The recommended time by the maintenance minder." He said I should use the synthetic oil and now I can drive up to 8500-9000 miles until the next oil change. What do you guys think?
He also mentioned after changing the oil that it was dark and a little low.
