Some good information from a Tribologist .
The viscosity video is interesting explaining how engines with timing chains chew up the polymer additives and I suppose that goes for wet timing belt engines as well .

The importance of priming a new oil filter video shows it takes 5 seconds to get oil pressure with a dry non primed oil filter whereas a primed filter has instant oil pressure .

The video cautioning against various aftermarket oil additives explains how they can actually damage the engine oil and are best avoided .

Good video suggesting the first oil change on a new engine should be done as soon as possible .

Fuel additives are good and have no issues with engine oils

I highlighted the same thing in a recent thread on here. Our 4.4 TDV8 engines have heavy duty timing chains which are crushing our oil at a molecular level reducing its protection property’s. It’s mainly for this reason I prefer to change my oil every 3 to 4000 miles. 2012 4.4 TDV8 Vogue Santorini black ivory leather

- wait until you find out about what gear teeth do to the oil in the gearbox and you will be changing this every week  2012 TDV8 Vogue (L322)

Damn! I better start changing my gearbox and different oil every 3 to 5k also....

Just kidding and I know I am changing the oil a little prematurely but it's 1 extra oil service a year and gives me peace of mind. 2012 4.4 TDV8 Vogue Santorini black ivory leather
