My 2002 ZX3 is to take 5w-20 semi synthetic,
I asked my garage to put in fully synthetic, MOBILE ONE (what color is
I walked into the service bay and caught the mechanic filling it up with the
default 10w-30 regular oil.
I complained to management & mechanic was to drain 10w-30 & replace it with
what I paid for.
How can I tell if this was really done? The shop is a local garage in about
which I have never heard a bad thing.
Any damage if they left the 10W-30 in the engine?
Thanks, in advance for any useful responses.
