Hi,
I have a question about low-SAPS oils. What really do they do for emission and danger not to use them on your car like VW 2.0 TDi?
Why am I asking this? Since oil is never or almost never gone to emission system, just may be vapor as from oil separator. So why do they required this?
Also I want to use lower HTHS oil for my own reason, as I do oil changes every 5,000 miles anyway, so M1 syth 5-30 is good. In my opinion and after reading on this forum and different articles about higher HTHS oils, it does last longer, but after 10,000- 15,000 is getting as low as normal syth oil anyway.
Well please don’t kill me right the way, lets’ do more rational way.
One more question, why do the modern diesel engine use same oils as gasoline engines?
Thanks
