Rated 5 out of 5 by from Lubes the hull I have purchased several gallons of this motor oil. This oil works perfectly in my 1964 Amphicar (it's a boat, it's a car). This oil does not have the harmful ingredients that new cars require so I'm not killing my engine everytime I drive to Lake Mead. Pretty much floats my boat without a problem.

Rated 5 out of 5 by from How to get 550,000 miles on your Volvo Purchased my 1987 Volvo 740GLE new and with Castrol GTX-HD-30 and personal attention to oil and oil filter changes, the car has logged over 347,000 miles with NO major engine repairs needed. Great car, yes, but abundant credit due to fine lubricants produced by Castrol!

Rated 5 out of 5 by from Only oil to use My 1987 Volvo has known nothing but Castrol 30W since purchased new at that time. With attention to maintenance the car now has 537,000 miles and has never had any engine or transmission work. A great vehicle kept well thanks to Castrol!
