What I'm getting is that TRD haven't proof read their page before putting it up.
Everyone on BITOG that's been paying attention knows that these engines were built specifically for TGMO, and that TGMO is more than adequate for track use...
I can't believe that the "performance" arm of Toyota would purposely throw away "huge" amounts of horsepower, fuel economy, and most importantly cold weather starting.
Thus my conclusion that it's a typo.
wemay, they are referencing an A3/B3 lubricant, which has to have an HTHS of 3.5 or greater...some on this board would accuse it of "really being a 40" due to that fact.
It's not an economy oil, nor CAFE, it's typical of HDMO and European long drain.
And interestingly (I've been called a purveyor of misinformation for making this statement before)
Quote:
Characteristics of oil film in high temperature (Comparison of HTHS viscosity)
The oil film is 17 percent thicker than the general 0W30 oil and it could also produce the same thickness to 0W40 and 5W40 in high temperature. It could be used safely
for turbocharged engines which require steadiness when in high temperature. Also extremely low friction characteristics of the base oil will give a great engine response in
both high and low rev.
