Is it possible to tell if you have mobil1 other than some sort of $ lab test?
Some funny, odd answers above.
Only thing I can think of, and this just shows if its synthetic or not, is to take a sample, put in a small jar, then get some conventional oil of the same viscosity type (5w30 for example) and put it in another jar, then put them both together in the freezer overnight. Freezer is at around 0 deg F, so Mobil 1 will be a tad thinner (viscosity lower) when you pour it out.
