Sludge and varnish build-up can be dangerous so if you suspect a poor grade of oil has been used, your car has high mileage, or gone past the service date, it will benefit from an engine flush. We recommend PROMAR additive ($35 per shot) for engines with hydraulic lifters and high mileage especially Mitsubishi, Subaru, Mazda V6.

Excellent service. I've been using these guys now for a number of years and have never had a problem. Always on time and very reasonable costs. I get both our family vehicles serviced here every 6 months and would recommend them fully.
