I went to Valvoline Instant Oil Change on Warwick Avenue, in Warwick, Rhode Island on 6/13/07 for an oil change. Unfortunately, the employee that performed the oil change did not tighten the oil filter properly. As a result the oil slowly drained from the vehicle resulting in major damage to the engine. Ultimately, I had to have the engine replaced at a cost of $2000.00... The manager at the Valvoline Instant Oil Change denied any wrong doing, even though the mechanic that I brought the vehicle to (because of the engine noise) had to turn the oil filter two full turns to fully tighten the oil filter, and said that there was virtually NO oil in the motor. This was 5 days after the oil change.
