10000 km is actually really not a long oil change interval it's pretty short especially for a dual flow filter. 12000km is more in line what you should be running that filter. Top 1 oil is very good oil and from the US. There synthetic is group III base stock.

On a gas vehicle using say a Baldwin your wasting money if your running it less than 15000km on any synthetic oil.

But here's the deal, If you guys really and I mean really want to save yourself money on oil changes you will pick a oil and stick to it and pick a filter and stick with it and run it for 15000km and then get a oil analiis done with a TBN.

Not only will you now know how long you can run your oil you will know the state of your engine, you will know if your running a aftermarket air filter if it's doing a good enough job keeping particles out of your engine, if your leaking coolant in your oil or fuel in your oil and a bunch of other stuff.

Some might be surprised how far you can run oil and it still have a good high TBN especialy diesel oil. I plan on doing at least 3 on mine so I see how well my DIY dual bypass system is doing.
