Specialist oil is a con. Plus all the other unnecessary garbage the salesman Daniel tried to add onto my service. I should have told him to shove it, but as i’d already payed up front, and was at work and stressed, i decided to take the hit for the bs engine oil extra, but refused everything else he tried to add on. What a total con and rip off. My car didn’t even return clean, and i’ll be inspecting the work recorded on my invoice. Avoid! Avoid! Avoid!
