I used an angle grinder with a very thin cutting blade for metals, sir.

The reason that Valvoline is not all that great is the rating. The CI-4 with the SL automatically will reduce the amount of additives in the oil to meat the SL standards. You want your diesel oil without the SL, but better for a gas engine. The Zinc content will be well below 1200ppm and so with the Phosphorus due to it's API rating. TBN of 9.5 is not bad but there are better oils. It will easily do 10000klm with the oem filter.

Hopefully we can get a database of Local sold oil oil test started up soon.
I'll have my oil tested after the 5,000 kilometers mark at the Cummins engine distributor that miko101130 posted above to see how it performed. But since the previous oil is a Mobil, will the test be accurate for the Valvoline since this is my first oil change?

I will shift to Mobil Delvac MX soon and see how it goes.
