This is interesting. I suspect your winters aren't too cold there? But 10w40 is still pretty thick for that two year-old GDI V6 vehicle. Is that GTX conventional or sythetic? Is it using oil when thinner gets used? My daughter has the same engine (2016) and it really likes 5w40 full syn. Uses only half the amount a 5w30 would use there.
The post ended up in the wrong thread. Yep, it’s plain Jane white bottle GTX SP conventional. A west coast car running on the Sea to Sky highway between Vancouver and Whistler.
The first 3 oil changes were 5w30 including the two free ones at the dealership and I did one using 5w30 Petro-Can synthetic.
I’m not extending oil change intervals, usually around 50% OLM when I’m at my daughter’s place.
Why this oil? I bought 6x 5L jugs that worked out to $19 USD each including tax and environmental fees.
No use paying for premium synthetic for 50% drain intervals.
But, I also bought 6 x 5 quart jugs of M1 0w40 SP and 28L of Delo 5w40 to use up after the GTX is gone.
I want zero oil consumption for the emission control system and clean oil for the timing chain.
Edit: I think your daughter’s 2016 might be the previous generation LFX 3.6L and the newer ones have the LGX.
Squamish got 2500mm of rain in the last 12 months, which works out to 8 feet in the old money. On her last trip to Vancouver General for an overtime shift, she said that little cars were getting washed off the highway.
So the next day off came the worn Nitto EXOs on her 3500 and on went directional Hankook RW-11s in 275/65R20, and I’m waiting on 17 inch wheels for the Acadia that are coming from Toronto. Every where else is sold out.
17s instead of 20s will allow me to use LT tires, 245/70R17E with a deep tread for safer operation in heavy rain. I have a set of General Arctic I bought last year, if those hydroplane, the new Toyo M655s might do the trick.
On her last OT shift at VGH, she had a delivery in the parking lot, another mother almost bled to death and two nurses got punched in the face.
And people wonder why there’s a nurse shortage.
