To make the flow rate test more accurate you had to completely remove all air out from the test tube. Fill the tube to the brim drop the steel ball in, cap it off and clean the spill so there won’t be any air in the tube. If you can also make a small stable flipping stand as well so every tube will flip up straight all at the same time and make sure the tube holder are tight as well, holding it by hand cause some of the tube to be not in a complete 180 degree angle because your hand is not a completely flat surface or stable enough and those factors can affect your results, especially those air bubbles gap.
Len Groom, TPM at Amsoil cites that their V-Twin, Dirt Bike, and Metric motorcycle oils are all premium or OEM+ price point thus the $16/quart price. The dirt bike and Metric oils were tested and tuned with their dirt bike sponsorees specifically for the clutch grab/friction.
Usually they are printed either - on / around the cap - on the bottle - under the bottle - Or on the label They are printed really tiny most of the time like those fine prints found in a social media user agreement 🫣.
Personally, I have never tried 300v before. But from my understanding, racing oil is designed for shorter drain intervals. Thus, that doesn't fit my need for touring. Tried 7100, really good gearshift feel.
Hi there, I felt that both brands are okay. Motul 7100 feels easier to shift initially Amsoil Metric lasts slightly longer So, depending on which u prioritise.
Amsoil Metric stated 2x the recommended or 1 year but it's up to the user to judge. I do 5,000km or 1 year for my Yamaha Super Tenere altought the service manul mentioned 10,000km.
@@zwc888 Thanks for the response. Just to clarify one more thing, is the change interval the same for engines with a 1-liter oil capacity as for those with a larger capacity?
@@salmanriaz5184 Nope, usually 1-liter oil capacity engine change interval are like 4,000 to 6,000km according to maker service manaul. Lower oil capcity = Shorter drain interval - that's usually the case.
Tried 4T on our 125cc. Decent engine oil too, just that the price point is too close to Metric (if I'm not wrong SG$2 apart). Thus, we go for Metric, which is more bang on the bucks.
I have no idea either, I guess all these brands (Amsoil, Motul, Liquid Moly, Putoline) that focus on lubricants don't believe there is a need for that foil seal.
@@zwc888 "By the way, is that motorcycle of yours used for road racing or just cruising? Because there's this Amsoil Performance 4T 20w50 that offers more protection than that metric. It's also cheaper, and I don't know why. Can you also do a review for that, please?"
@@miguelpaneda1607 For cruising & city riding only. I tried both 4T & Metric on my Honda From (125cc). From the butt Dyno standpoint, no difference. But on the visocity dropped, 5:31, you can see the 4T (2nd tube from the left) seems to have dropped a grade whereas the Metric (1st tube on the left) looks as good as new. I also went to explore the data sheet on both. Metric contains more cleaning and antioxidants as compared. Thus I guess that explained the price point.
@@zwc888 well its not about the looks but the feeling of the oil being cooked inside the engine.. i tried the metric on my pulsar 180 (rouser 180 in philippines) the metrics good on acceleration but seems to break down on long rides but the 4t doenst gave me any leg stress, ,even on the traffic...maybe that metric of yours is good for thw engine that has liquid cooling system
You are saying that because you never used it. Royal Purple always lost to Amsoil in independent third-party testing, so it makes Royal purple snake oil 😂
