Sorry, yes the most recent oil change, & last 3 were Motomaster. The inittial one was Motorcraft
The first oil analysis from fluidlife was the factory installed oil Motorcraft.
The next 3 samples, sent to AGAT labs, have been Canadian Tire Branded Motomaster Formula 1 Ultimate Protection Synthetic motor oil it was manufactured by Shell & re- labelled for Canadian Tire.
Yeah we get some cooler weather, haven't had too much of a cold snap, only around -7 deg Celcius (19 F) today, & in that range for the last week, but we were seeing -20 C (-4 F) a couple weeks ago.
In Summer temps we will see high 30 Celcius range 34-39 (102 F) We usually see a couple 2 or 3 weeks with temps in the -40 or below.
I would rather run a synthetic 0W-30 in the winter if I needed, than rely on my fuel thinning it down for me.
I started using a Pennzoil Platinum, & will probably stick with it. It has a stamp recommending it for turbos, & I think it is supposed to help with LSPI that the Direct Injection is prone to. I can get it for around $30.00 for a 5 L jug when its on sale at Walmart or Canadian Tire.
