i don't know who this guy is or his credentials, and i akin this experiment to a well-done high school science project in terms of methods/equipment/conclusions. but i found it interesting nonetheless.
Totally useless test that does not represent what happens to oil in its intended environment.
As for Royal Purple in order to get true synthetic group IV PAO or group V Ester oil you have to step up to their HPS line of oil. I don't know if their motorcycle oil is group III conventional oil labeled as synthetic or not, if they are following the API/JASO guidelines then it likely is a group III conventional oil labeled as a synthetic.
The Royal Purple oil you see in the photo is a group III conventional oil labeled as a synthetic. Mobil filed a complaint against Castrol for labeling group III conventional oil as synthetic oil with the National Advertising Division (NAD) of the Council of Better Business Bureaus, but NAD ruled that Castrol could label their conventional oil as full synthetic.
That decision was a horrible decision as now any manufacture can label any group III conventional oil as a full synthetic oil.
Redline is what I use in all my combustion engines because they use group V Ester based oils and group 4 PAO based oils both of which are true full synthetic oils.
I run Dimple magnetic drain plugs in my 2018 Yamaha Star Venture, I like the Dimple drain plugs because they are a very high quality piece and the magnets they use are very powerful.
My old Victory Cross Country Tour I bought a magnetic drain plug from a place called Witch Doctors but I ended...
I rarely ever change a drain plug crush washer and I have never had one leak on me. I have used the same crush washer many times and sometimes never replace it with a new one.
I do however use a torque wrench to tighten the oil drain plug, no matter the vehicle I only tighten to 14 lbs ft of...
I was just wondering about using this stuff in a bike. It says annual protection, and guaranteed for 20,000 miles. That would translate into quite a bit of time between oil changes, especially for a bike. Would you use this in your bike? Would it hurt anything to try? I just changed my oil, but...
