Petro-Canada publishes them as CD & GL-3 as well. I use them all the time in shared motorcycle/engine oil and V8s with heavily loaded valve trains.
TO-4s are not cheap to buy especially the synthetic multi-grades.
Look up supertest
www.lubricants.petro-canada.ca
They show P=1000 and Zn=1100, but VOAs show 20% higher. TBN is usually around 10
edit; asleep Delvac 1330 is in my daughter's 13 Matrix and son's 13 1500 5.3 SLT, both good for 14k km, what ever that is in miles. (x.62)
Does "friction enhanced" mean "friction enhanced" or "friction reduced". The latter might be contra-indicated for m/c transmissions.
I bought the CPC straight 40 above for a m/c transmission (where it seemed OK) but ended up using it in the car engine (at about 50% with Delvac MX 15/40) as well.
I looked for GL-3 or 4 for the car transmission locally but didn't find any, though there is apparently a Redline stockist at the other end of the country.
Ended up buying this stuff in Japan, though I considered just using engine oil.
Havn't actually changed it yet, since I can't remember where I put it, but I have to move house soon so it'll probably turn up then.
