10W40 castrol

I use this during summer & change to 10W30 for winter. My cars/trucks are 1995,& 97 &99. But Walmart quit stocking the 10w40, now I must order to store. Bummed. disclaimer: images are from internet & not my actual rides but are close twin to my actual vehicle.



the quality which is a perfect match for my 92 toyota tercel


GTX was priced right

I was happy with the pricing on this product, and GTX is a pretty good brand. Worked for me.


Castrol in everything

Have used Castrol GTX 10w/40 in all my engines for many years now. My higher reving motors get Castrol 20w/50. Love the 5 quart bottles, need only one container for a single change in my car or motorcycle. Great product.
