MaxLife 5-30 is an awesome oil!
Where does it say that "CAFE" restricts the use of 5-30 oils? This is just another thick vs thin thread.
It does.
The CAFE document was posted on BITOG some time back by a poster.
Please repost where CAFE requires 20 wt oils in engines calling for 20 wt. Warranties might, but CAFE. Just askin.
Right. CAFE regs require manufacturers to achieve a fuel economy standard across their range of models. How manufacturers achieve this standard is up to them. Lighter weight, better aerodynamics, different transmissions (CVT, DCT, etc), direct fuel injection, turbocharging and lower-viscosity oils are some of the techniques automakers use, but none of these techniques is mandated.
CAFE standards have been around for decades but German marques still specify 30 or 40 weight oils and GM just recently began transitioning from 5w30.
