That isn't quite true. This past November I replaced a fill of QHorespower 5W30 with Petro Canada's 0W30. The owner's manual allows the use of a 0W30 for cold temperature climates. Hence it has been in all winter.

I may come across as a 'know-it-all', but I learn something everyday - much to your point above.

Searched in PDF version of my owners manual, and voila:

"Cold Temperature Operation
If in an area of extreme cold, where
the temperature falls below −20°F
(−29°C), use either an SAE 5W-30
synthetic oil or an SAE 0W-30
engine oil. Both provide easier cold
starting for the engine at extremely
low temperatures."

It would appear there's some wiggle room for the perfectionist in me to make use of a 'winter fill'. Thanks for pointing that out.

I find it very hard to believe that this triple digit Fe # can be attributable to winter idling (assuming that the actual Fe count is correct

)


Not winter idling directly, but if it results in fuel dilution then definately in engines with iron or steel cylinder bores.

BigTallV, how much more to add the TBN test?

addguy, does Petro-Canada OA include 40C vis and TBN in the 25 buck price?

Not sure.....I think so. On their website, they set out what their oil tests consist of. I phoned a bulk distributor a couple of years ago and was told each kit was $25.

It was an additional $25 CAD (plus tax) for the TBN test. You specify it on their "Additional Testing Order Form". Found on this page: Fluid Life Corp - Advanced Oil Analysis
