I called this company to get an estimate for an oil change for my 1991 Mercedes 350 SD Turbo Diesel. The person I spoke to representing this company said they could do the work and an appointment was set and the work was completed.

My son noticed the receipt said Castrol GTX 20/50. He did not believe the correct oil was used for my Mercedes diesel engine. My son instructed me to return to the shop and look at the API rating on the label. He said “S” rated oil is used for gas engines and “C” rated oils are used for diesel engines. I spoke to Mickey who was very kind and assured me the correct oil was used but I noted the API label said “SN”. My son was not satisfied and went to the shop to specifically look at the label on the drum of oil. Mickey Jr. showed him the drum, my son verified the API rating was "SN" (Castrol 20W-50) (it did not say diesel).

In further discussion Mickey Jr. said he could order “the correct oil for my car but it would cost extra”. My son told Mickey Jr. we have lost confidence in the work this company performed and wanted a refund so I could take my car elsewhere to get the proper oil change. The request for a refund was denied. 

Mickey Jr. spoke to an elder gentleman. This person asked my son what seems to be the problem. When my son tried to discuss his concern, this person said “that oil is the same oil we have used on every diesel engine that enters this shop”. My son made a comment that this shop is using the wrong oil in diesel engines.

What was more shocking is this person said “who made you the f-ing expert”. My son replied he was not an expert but stated the API classification codes that are explained on the internet “C” vs “S”. He also brought up the API ratings listed on the back of oil, specific to diesel engines, are “C” ratings. The elder gentleman told my son to “get the h*** out of his shop” and walked away.

Before this review was written I called Castrol/USA. I wanted to do more research before writing a bad r
