This does prove that it is better to prefill your oil filter when possible. You can't prefill the oil filter on engines that have a filter that attaches to the block sideways - but if your engine has a filter that allows you to fill it with oil as you install it.....it is best to do so.

Even the horizontal filters can be partially loaded. The media holds quite a bit and if they are loaded up and left standing the level drops as the oil soaks in and through.
I haven't done any kinda Deep Dive on it, and some YouTube mechanics are vocally against prefilling because they, actually, I've only seen one, He says it's too easy to allow harmful contamination into the filter that will be pumped into the engine. I'm not in agreement. Pay attention and Don't is my thinking.

Engines that use the low viscosity oils don't like the 15-40 that the old school Suzuki design works well with have lifters and, as I understand it, the clearances are so small that the lifters can't operate right. Anyone who has more on that is invited to straighten me out.

I have used Rotella T 15/40 diesel oil in my bikes for as long as I can remember. I buy it in 5 gallon plastic buckets. Last time I went to buy some there was none in the store, but they did have what appeared to be a Castrol equivalent.. "Castrol 15w40 CRB Multi " I bought a bucket.

A few days later I changed the oil on my CJ750 and topped up my 2001 Dodge Ram 2500. I checked the oil on the CJ after a couple of rides and was surprised to discover the level was spot on, ( it had always burnt a lot of oil ) I put it down to the possibility that I had overfilled it when I changed it. 2 weeks and 1000 KMS later the oil level was still perfect. It was the new Castrol oil that had cured my 6 year old problem.

I put half a liter in my previously oil burning Dodge, and it stayed spot on for the next 3000 kms when I changed the oil again.

PS, I'm always a bit leery about changing something that I have been using for a long time, but I am glad I did. If you have doubts ( and I would not blame you ) and have ao oil burning engine give this oil a try, no need to buy a five gallon bucket, just add a little to your regular oil and I bet you would notice an improvement.

What’s a CJ750? Chang Jiang CJ750? Looking at the specs for the Castrol CRB Multi, it doesn’t list JASO MA/MA2, so I wouldn’t put it in a wet clutch motorcycle. I know nothing about a CJ750.

At least Shell Rotella T4 and T6 have the “meets of exceeds” JASO MA/MA2 language on the container (although they technically don’t have the actual JASO approval). I trust that Shell did their homework and just decided not to spend the time and money getting the actual approval.

Yes a CJ 750 is a Chang Jiang 750. It's a copy of a BMW R71, made on the original tooling supplied by the Russians.

All I know about oil is knowledge gained from my experiences. I just take note what works, even if I don't know why.

Well….if the clutch starts slipping, you can add that to your experiences. Maybe the Castrol will be okay, but without the JASO MA/MA2 language or approval, it won’t be going in any of my wet clutch bikes.
