I dont know what part of the country you are in, but I asked what an oil change in my 01-E (in between FSS schedule) and they quoted $90 with synthetic oil. On my 92-S it was $53.44 (9 quarts regular oil/ filter/ labor) the last time. I doubt they gave you synthetic, I asked about syn. on my S and it was over a hundred and they told me not to do it.
