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.


Good stuff.

Got sold on Castrol back when I owned air cooled VWs. Now I run it in all my engines, both car and small engines.


Outboard 4 stroke oil

Best oil for outboard 4 strokes. If you don't use owner manual oil. This is best at fraction of price. Api codes match most manufacturers suggested codes


GTX was priced right

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