Hello everyone! I would like everyone opinion as to which is a better oil between these two. The vehicle is a 1994 landcruiser 1HZ indirect injection NA diesel. Both oils are 15W-40 CI4 rated mineral diesel engine oil. The Castrol Vecton has ash content of 1.5% while the Turbomax at 1.29%, which is oddly low for CI4 rated oil imo.
Is lower ash better for the engine longetivity? This engine does not have any emission system such as DPF etc. The diesel fuel used is Euro 5 standard which has 10ppm sulfur content. I have attached both engine oils data sheet below for your viewing.
I would greatly appreciate any input on this. Thanks!
