Found a 'new' line of oils that doesn't seem to have been discussed on this forum, and might be of interest: Irving Company Oils. Link to their lubricants site is here: http://www.irvingoil.com/pr_business/pr_lubs/ Their passenger car dino oils seems to be fairly average; and they don't have any spec sheets on their synthetic passenger car oils; but the oils that do seem like they might be of interest is their 'IDO Universal' line of HDEO's. The specs for these are here: http://www.irvingoil.com/dloads/infosheet/IDO_Universal_web_0905.pdf In this line, they seem to have 10W-30, a 5W-40, and a 0W-30 grades that have really good specs - look at the ccs numbers for the 5W-40 and 0W-30 grades, and the TBN for all of them. They seem to be pretty stout for this type of oil. I don't have prices for this oil to report, but they seem to be distributed through MacEwen gas stations, which probably means they aren't exactly a bargain, but who knows. It also may mean they are only avaliable in Canada, unless there are Irving distributors in the US. The one comment I would make about the oils is that the 5W-40 grade seems to have good numbers, and if it is decently priced, it may be a Canadian equivalent to Rotella-T 5W-40 oil, which many in the States seem to feel is a great deal for cars that need a 5W-40 oil. For those in Canada that need a 5W-40 oil, this may be another option. Hope this helps!
