Thanks for every ones thoughts. I misstated the frequency of oil changes – I do it every 3K miles not 6K. I agree that synthetics are a higher quality, hence, the higher price but I’m still not sure if there really is a difference between Pennzoil 10w 30 at $2.50 a qt vs. Exxon 10w 30 at $1.20.
Yea, if I had $45K in my 69 camaro I’d for sure would go with synthetic because I’d want the best for the car. But as for my 98 Avalon that is not worth very much…. I’m ok with the $1.20 qt.
JamesJ, your comment helps to support my theory.
