I tried looking in the archives for precise information. I'm unsure if I should add to an old discussion or start a new one: this is one of the few times I've participated in a group discussion. (Please let me know if I have it wrong.)
Question: We have bought a 2002 Miata, (called MX5 in Australia) and I am just a little worried about what might be excess oil, damaging the engine. (The last owner might have slightly overfilled the oil.)
The level on the dipstick reads above the full level, about 7-8mm above the F line. The oil pressure gauge reads half way between the half-way mark and the next mark (next mark is at one o'clock.)
Just exactly how far in millimetres (or parts of an inch) over the F line will cause problems?: I was under the impression car engines had an oil pressure relief valve to avoid engine damage. Perhaps not?
Otherwise we are well pleased with our purchase.
