Rated 4.1 out of 5 by 7 reviewers.
Rated 4 out of 5 by Great for import 4 cylinder engines Always use gastrol on my Tacoma and used it in my Altima and pre-Tacoma Toyota pick up. Never let me down yet. November 18, 2016
Rated 1 out of 5 by Disappointed l am disappointed with the service I was provided during several visits to a Pep Boys shop in Fort Walton Beach, FL. - Once they installed the incorrect grade oil without consulting me--after I brought the issue up I was told it was better for my vehicle--the point is you shouldn't take liberties with my vehicle without consulting the customer first - They put an additive in my gas tank without consulting me--I had already put a treatment in my vehicle and was concerned about the effect of a different treatment on top of it - On another visit I wanted a particular brand of oil and was serviced with a different one--the counter man did not listen to what I asked for - After one visit I attempted to check the oil and the OEM oil cap was over torqued and broken--I could not remove it. I returned and Pep Boys removed the old cap and replaced it with what seemed to be a less capable (not OEM) cap. I appreciate that they replaced the cap but the extra trip was inconvenient. Overall, the customer service needs to improve. The individual behind the counter needs to do a better job of understanding what is being asked for and the workers should not deviate from the plan unless coordinated with the vehicle owner.

Rated 5 out of 5 by best motor oil there is Castrol has helped me take my Mitsubishi to 287654 miles so far, and my Mazda to 142700. August 23, 2015
Rated 5 out of 5 by have been using Castrol oil for 46 years. The only oil I trust. I own a classic 1970 VW Beetle convert. and a 1983 Classic Mercedes 300SD diesel and both engines are clean internally.Occasionally I have to replace valve cover gaskets and the internals are clean with no sludge build up. I also use it in my wife's 2014 Honda Civic. Great oil! June 20, 2015
Rated 4 out of 5 by Castrol GTX 5W-20 Conventional No complaints. December 26, 2014
Rated 5 out of 5 by great product Very appreciative for Pep Boys to think about their customers during the holiday season in offering their "$15.00 off coupon," for any 5 quarts of motor oil and an oil filter. As your products exceed OEM, I shop for my other than automotive needs, as well. The Castrol 5-20 oil for example was purchased for my snow blower. December 22, 2014
Rated 5 out of 5 by I Have been using Castrol prducts for years I have been using the Castrol products for over 45 years and have never had any issues/problems due to oil breakdown--- August 13, 2014
