so, because i had some starmark issues, i took my 1997 c140 to a m-b dealer. were it not a starmarked car, i would never see a m-b dealer.

when i brought the car in, i asked them what lube oil would be used. i was told a castrol syn. i said NO. in the 24,000 miles of this car, only dino had been used and i did not want to change that. so, the m-b dealer said that they could use castrol gtx. i stipulated dino lube oil when i signed the ro.

i picked up the car today. paid the tariff. and then noticed that the lube oil change designated a castrol syn had been used. and i was charged for syn.

i got pretty pissed off. not about the higher price of the syn, but that my instructions had been ignored. whereupon, i was told that the invoice was in error, that dino had in fact been used.

i had to accept that. but tell me, what do you think about syn replacing dino without any advance warning?

more to the point, for 8.5 quarts of oil, i was charged $46.75. is that the price for syn? or the price for dino?

if syn was used, then what do i want to do? change it immediately?

this c140 has never had used syn and i have questions as to the substitution of syn for dino. especially when the substitution was made in defiance of my instructions.

all ears.
