Store Reviews
Stephanie S
I switched from the dealership for oil changes and followed the closing of Stratham Tire in Newfields to Portsmouth. This is my fourth (fifth?) visit and I continue to return because of the friendly, efficient and informative service. The cost of a synthetic oil change is reasonable (the dealer was outrageous) and while keeping me informed, Sullivan doesn't pressure me to buy the service repair of the day like the dealership used to. 3/30/2026

Total pro’s. They have clear information with no upsell crap! I have used them before and will continue to use them for the long haul. Very knowledgeable and helpful! Happy customer. 1/13/2026
