I know we use to with our racecar years ago. Can help prevent a surge in first start (was an issue with our race motor but tolerances were a lot finer on that) but this wouldnt be an issue with these motors. Also means your oil doesn't drop on the stick by 1/8" after changing/starting it. Again, not much of an issue.

And messy if you have a horizontal filter.

It's a throw back to the days when oil pumps wouldn't prime without a full filter. Totally unnecessary and not recommended due the risk of contaminating the clean filter.

the oil filter on these motors doesn't see full engine oil flow so even with an empty filter on start up the important spinning bits are still coated in the important slippery wet stuff.

Just out of curiosity, whenever I change the oil and oil filter, I sometimes clean out the Earls filter as well.

As part of my service routine, when I finish the service, I make sure that I have WOT and then crank the key over for ten seconds.

This makes sure that oil is going to the turbo.

Will this also fill the oil filter while this is happening?

Yes. But do the 10 seconds in 5 second lots with a pause. Then the starter motor will be your friend

I do this as well mate, although erry time I take it off the filter is always full but the lines have drained out.

So either the lines drain very quickly when you crack the first fitting on the filter and what vacuum would be there is released. Or the just do it anyway and the only benifit is your priming the filter a little and the lines fill on every startup anyway. Not sure.

As for the engine oil filter I think it benifits from being fully filled and has an anti drainback valve for future startups. I fill it about halfway before installing it anyway.
