I'm trying to persuade my father to get his car filled with synthetic oil to cure a problem with emulsion under the filler cap. There's no coolant leaks - the engine has been pressure tested so I'm guessing it's due to cold starts, or more accurately, cold stops.
He seems to think that synthetic is needless when he only does 3000 miles each year, and rarely goes over 40mph. The 40mph bit is a blessing in disguise, his driving is shockingly clumsy and not at all systematic so we're all better off if he keeps it slow.
I think a synthetic oil would be far less hygroscopic than a mineral oil and would probably eradicate the problem. Also, he could probably reasonably leave it in the car for 8000-10000 miles without causing any problems.
Any thoughts, anyone?
