Author provides (and exhibits) no credentials and is sorely out of date as regards change intervals. In a real article one does not use "I hear" but rather provides citations, i.e. footnotes.

Just for fun, compare to: http://papers.sae.org/2007-01-4133/

This guy doesn't seem to have any idea how viscosity is measured, or what the numbers on the top of the container actually mean (why the W in 10W-30). He never mentions viscosity index and contradicts himself when he says most engine wear occurs at startup (when the engine temp is the same as surrounding conditions) but ambient conditions should be ingnored.

Liquid cooled engines tend to maintain a more uniform running temperature after warmup but the oil has to flow from the time the engine temp is the same as outside conditions (startup) to the time the thermostat opens.

All right! BMWMOA has discovered BITOG!

I don't trust anyone who pushes Pennzoil products and owns both a Ferrari and a Lamborghini.

Require credible citations and references? That will end every oil and fuel thread on the forum.........

OK, I'm good with that.

sounds like we have a few people that need to start a new oil thread that's correct , authoritative,i.e., footnoted & then we'll have a worthy target to start in again?
