3K miles with dino oil aprox 22 dollars with a good filter
5-7500 miles with syn 33 dollars with a good filter

anyone see a problem here?


To make the math easier for the dummies out there:
dino: 3k miles $25
syn: 6k miles $50

Same price (or better) for dino and synthetic.

This subject has been discussed many times. I'll have to dig up some links and put them in the FAQ.



Your numbers don't jive with typical oil life and prices. Dino oil will last about 70% as long as synthetic. And prices of the oil are usually 60-70% less expensive. I still find API certified oil for 1.00 per quart once in a while, but 1.30 is very normal.

What is the best price you have found on Mobil 1? I think i have seen a sale or two that got the price down to be just over 3.00.

I wont get into the performance aspect, but conventional oils still have a fairly distinct price advantage.

Oh, and seals in cars do form a chemical equilibrium over time with the type of oil used so there is some merit, even if minor, to staying with what you have used. Feel free to dispute this, I guarantee my source is more credible than anyone elses.
