Take the car back to get the CEL diagnosed. If I had to guess it could be the following:

- sometimes they check the air filter during oil changes. If they didnt put it back in properly or close the box right it could trigger the CEL. Also, one of the hoses might have gotten knocked off in the process.

- The PCV valve is sucking up fumes from the ZMAX they put in and its triggering a weird reading in the O2

- Guy didn't fully put in the dipstick or tighten the oil cap causing a slight vacuum leak. On some European cars (VW) the car won't even idle if the dipstick isnt fully inserted allowing air to come in.

Also tell them not to put in the ZMAX next time. If you feel like pushing it, ask them to drain it out again but the problem is those oil additives stick to the metal and dont always drain out fully.

Yeah according to their advertising, it actually soaks into metal. That's what would upset me -- if it really soaks in, then it's pretty much irreversible. It's not like they can suck it out of the metal.

Well, maybe owner of this particular vehicle just got permission to drive the piss out of it and blow the engine, if that's true Semtex
