The SDS sheets all indicate different mixtures.

By "rated" I add "certified" since a number of oils claim to meet or exceed JASO FD but have not actually been certified (perform and pass the required testing, submit application, pay ~$260 fee). Certified oils have the FD symbol and certificate number on the bottle, they don't just claim to...

The viscosity of the unmixed oil does not necessarily translate to the viscosity of the residual oil in the hot combustion chamber after a significant fraction has flashed off and burned. We don't know the viscosity in the engine. Of the four oils mentioned above, Echo has the highest unmixed...

Even though it is made by the same folks who make the VP oil, Lubrication Technologies, it looks like it is not the same oil. The flash point is 92C. VP lists a flashpoint of 80C. It also has a higher viscosity (43.7 vs 36.2 at 40C) and a little higher density than VP. The composition is listed...

Lucas is not alone in this. There are well known, well-respected oils that are not actually certified despite their marketing claims. An obvious example is Amsoil. They even claim to have performed the necessary testing to qualify for the certification. So why not certify it? If they have...

Here is the official list. Lucas is not on it. https://jalos.or.jp/onfile/pdf/2T_EV_LIST.pdf If they are not on the list, and don't display the FD symbol with certificate number on the bottle, they have not performed and passed the testing required by the standard and submitted an application...

After some digging and finding SDS sheets, this fuel is made by/for VP Racing and carries the VP Racing JASO FD certificate, using a full synthetic oil in the mix. Its composition is identical to the Powercare fuel you find at Home Depot, also from VP Racing. The VP Racing branded fuel (in the...

My infrequent use of two-cycle engines makes pre-mixed fuels attractive despite the price. I noticed this Supertech pre-mixed fuel, which is significantly less expensive than any other that I have found. True reviews of it are surprisingly difficult to find. The oil in it is JASO FD certified...

Another table I find easier to read (taken from a post in this forum, I don't recall who originally shared it)

Any help with finding the relevant section of this 383 page document?

Dug it back out of quadruple bagged and tied garbage...sorry, slightly out of focus at the sealing surface, in person it looks fine.

Second filter cut open today... 2005 Toyota Sienna with 150,101 miles on the vehicle, 6,573 miles on the oil and filter. Mix of driving, though >60% was on road trips, and I normally keep it under 75 MPH. Out/Off - STP synthetic 5w30 (the shop put this oil in after replacing the valve cover...

I never imagined that I would actually be cutting filters open, but here I am... 2008 Honda Civic, 99,463 miles on the car, 7,504 miles on the oil and filter; mixed driving, mostly to work (21 mile RT) with some longer trips added in Out/Off- Mobil 1 5W-20 with 1 qt Mobil 1 Extended...

2005 Toyota Sienna owned since it was new, passed 150K a couple of weeks ago. After the original factory fill it was Mobil 1 until a couple of years ago when there was no Mobil 1 5w30 on the shelf when I needed it, and got some PP, which I have used since then. I have some Mobil 1 Extended...

True, but that was a rectangle with a much, much smaller aspect ratio than the narrow slot. The flow characteristics of a narrow slot are different a generic rectangle.
