It’s basically the clutch friendly indicator of a lubricant. For motorcycles with shared sump systems (clutch is bathed in the same oil that lubes the engine), the JASO-MA2 rating more or less is the guarantee that friction modifiers won’t bed into the clutch plates and cause a loss of friction (and therefore a loss of power transfer).
I would assume they already have something that meets the “clutch friendly” lubricant need, I’m just not sure which one off the top of my head.
Wouldn’t hurt to sample it. At 5k miles the iron levels in my oil analysis on Amsoil 5w-20 was at 26 and got flagged in the analysis. The oil still had life left in it, but had taken a beating towing from the AL/TN border to Tampa and back during the hottest two weeks of the year.
Did lots of spirited driving mostly averaging between 80 to 100 mph on this oil, this car is very rev happy seeing between 3-5 thousand RPM occasionally in the highway but mostly stays slightly at or above 3000 RPM cruising at 80 mph with average daily drive times of 3-6 hours a day. Oil loss has been very minimal around 2-4 ounces. Before there was virtually no visible consumption.
Its for the friends KIA, a 2013 Rio and 2016 Soul, and my brothers Subaru 2022 WRX that i will be servicing in the future. But yeah may try it with the HPL PCMO for another 5k run for stronger cleaning if safe on seals and elastomers. We will see when i pull the filter for inspection. There is still some varnish at the fill port area and valve cover oil baffle. Gonna move to HPL premium or HDEO premium when my 12 quart case of the PCMO is consumed.
What’s your vehicle & use case? Sump size has a huge impact on OCIs… how many quarts does yours hold?
Have you looked into a Stahlbus/Valvomax drain plug? I went with a Stahlbus and am thrilled with it both for ease of drain & in-service samples, but I know @Trav is a Valvomax fan and I can’t knock that if it’s on his short list of good drains.
Yaris holds 3.9 quarts fill with oem filter. I prefer to use a larger oil filter so the actual capacity is around 4.3 to 4.5 quarts.
the woman’s accord is at 4k miles already, i’m planning on 12k miles and i’ll send a sample as i drain it.
Whats the accord oil capacity?
5 quarts is what i put in.
You’re not alone. I feel the same way. And I know I shouldn’t.
This time I ran the 0w30 HPL Supercar 10,000 miles. No indications of any LSPI events. Filter was very clean...not quite as dark colored as my first 8000 mile OCI...had three hard black balls (carbon?) about double the size of this period: "." Engine lost 1/2 quart in that OCI...I measured 5 quarts out, after it was initially filled with 5.5 quarts 10,000 miles ago, and I put 5.5 quarts in today to bring it up to "full". Before changing it I drove nearly 500 miles today at 75-80 MPH with a few sections a bit quicker, a couple of WOT for a few seconds (doesn't take long to be going much faster than legal) and with some Stop-and-go. Hand-calculated 33.4 mpg. I usually get in the upper 20's in a mix of suburban with about 20% highway with a mountain bike on top. Don't see a reason to run the 0w20 as spec'd for this engine in the USA. Amazing what can be done with a small turbocharged engine...
I'm about over 6000 miles currently with the first HPL PC5W30 fill and after a while around 3k miles, I noticed the vehicle accelerates better on light press on the gas. You should try giving your Yaris a spirited drive session once you feel passed the break in. I certainly noticed it on my vehicle.
I run the nuts off of it nearly every time I drive it lol but it was the light throttle stuff where I noticed the difference.
