Best oil for my 1.4T Trax?

[hardcore302]

I've been using mostly Castrol Edge (black bottle, non-EP) along with strictly AC Delco filters *UFI cap *. I've ran it strictly following the OLM. However, I remember someone a while ago on BITOG running some UOAs and saying that some oils looked on the edge of shearing at around 20%. Do you guys have any suggestions on oil brands and if I should still follow the OLM? Thanks. I don't mind spending a little more.

Any d1g2 or d1g3 should be fine for the OLM-suggested OCI

Maybe d1g3 will shear less than d1g2

Another option is dexos2 (blue logo) such as PP Euro L

Edge of shearing? I don't know if I've ever seen a passenger car cause actual mechanical shear in an oil on here, if the UOA were from Blackstone then there is no way to reliably discriminate a viscosity deviation between fuel dilution and mechanical shear. They also have shown difficulty in accurately measuring viscosity. Shear is one of those terms that's thrown around a lot and the vast majority of time it is fuel dilution or inaccurate viscosity and/or flash point measurement.

So having said that I'd use any oil that carries the specification or license listed in your owner's manual. As noted above a dexos licensed oil is a good choice.

Castrol edge pours out of the bottle at the thin end of the 5w-30 spectrum. If you want a 5w-30 on the heavier end, look at Supertech FS/Kirkland Signature or Quaker State FS

And for what it’s worth a UOA is a particularly poor way to chose an oil.

I've used whatever Dexos rated 5w-30 in mine for its whole life. Never used a drop between changes. I used to go to 10% on the OLM (around 6500 miles) now I change it at 5000 miles no matter what the OLM says. 96000 miles on the Trax.

Here’s a UOA from my wife’s 1.4T in her Buick. The oil was (claimed to be) bulk AC Delco 5w30 Dexos from the dealer invoice who did the last oil change. I change it for her every 5,000 miles (about 30-40% OLM) on these high strung turbos. They’re tough on oil.

2018 Buick Encore, 1.4L Turbo, 5,243 miles, AC Delco Dexos 5w30

Vehicle has only been serviced by the dealer car was purchased from. Found out the dealer has been installing the wrong oil filter since the car was purchased. It's a long story, but here's the thread if you're interested...

Did you ever get the dealership to admit that they were using the wrong filter?

No. I wrote GM corporate and they sent me a letter telling me they gave me a 120k mile transferable engine warranty covering all oil lubricated engine part failures.

Unfortunately no oil is gonna keep that turbo housing from cracking. Just helped a buddy swap one out and that's a tough job. Like brain surgery. When that P0299 pops up, you'll know it's time.

Better than kicking rocks I guess

Another option would be PP Euro L 5w30. It is at the higher end of the cst for a 30w, almost a 40w and held up better than Castrol and Mobil1 in my kids Volvo C30 both 5w30. The others would be use about 1 to 1.5qts between 7k mile oci's and the Euro L was right at full everytime. I personally would ignore the olm and just change whatever you end up running at 5k oci's. Good luck

Quaker State Synthetic at Wal Mart. That’s my thought
