Is anyone familiar with Red Line synthetic motor oil. I have used Castrol 10W60 for all oil changes, except the last one. My local Aston dealership used Shell 10W60, and my car is running at top performance. I would guess as long as the proper oil weight (10W60) is used, the brand shouldn't mean to much.

 

I disagree? the quality of oil is very important, as are tyres and ather critical components, some manufacturers spend millions in R&D others get away with the minimum.

In aircrfat applications only certain oil is recomended, in my AM I run Castrol 10w60 its cheap insurance for a very expensive to repair engine, and i replace it every 3000Km, in my bikes i run only Motul 5100, its the best semi for hot running bike engines , again its cheap insurance against wear during the critical; start up phaze when things are cold.

In life u get wots u pay for
