On the topic of dementia, I can't remember which thread mentioned the rising cost of motor oil. In any case, Pennzoil has a rebate when you purchase 2 x 5L jugs of their motor oil which qualifies for either a $20 or $30 rebate via prepaid Mastercard.
Pennzoil is on sale this week and I can attest that most motor oils have gone up in prices by several dollars this year. The only motor oil that has resisted price increases are Walmart's very own SuperTech motor oil and RS favourite, Kirkland motor oil.
For those of you who are curious about the Canadian Tire/Pennzoil rebate, take a look
