Preparing a car for any type of motorsports competition is an exacting exercise. The difference between winning and just running in an event can often be measured in the thousandths of a second, so competitors need to eke every last ounce of performance from their vehicles. That's why even minor in…
Another interesting point I've seen made is the question of: How much do you spend on gas for your car? And it lasts how many miles? Essentially for the cost of one tank of gas you get the better protection of synthetic oils. The $20 difference in my opinion is not worth saving.
Also- it would be interesting to have a story on building and breaking in a new engine- would you use synthetics? Is there a particular way to build an engine wherein synthetics would be useful as a first fill? How do the OEM's (Chevy, Porsche, BMW) ship their engines with synthetic new from factory? How long does it take to break in an engine? Does the "motoman" break it in like you drive it theory hold water?
Good story regardless.
Is this also true for the older car where the machinning tolerances are farther off? Like for example my 1970 Mini which the engine oil also serves as the transmission oil, can I use a synthetic oil?
