Which oil for Turbo DI

[Danh]

Using a d1G2/SN Plus oil in a TGDI engine is a good idea, but it won’t make much of an LSPI difference until engine programming is adjusted to assume it is in the crankcase.

For non-GM makes at least, engines exit the production line assuming the engine will be using a traditional, non LSPI-preventing oil and will be programmed to enrich mixtures under any throttle/rpm combination that conceivably could create LSPI. Merely putting in a d1G2/SN Plus oil won’t change this.

Once reformulated oils are dominant or required, programming can be changed and lower fuel dilution and better fuel economy will likely result. A reasonable question is what OEMs will do for owners of legacy TGDI platforms when this time comes.

^^^If you own a TDGI vehicle in which the engine is supported by a tuning company/software/hand held device (Cobb, SCT, EFI Live, HP Tuners, Livernois, Hondata, etc.), and get a custom tune (or even a 'canned-off the shelf' tune) from them, most of the time they actually do adjust the fuel trims downward to lean it out a bit, to get a little more power out of it as a matter of course.
So that is one way to achieve the above before the dealers do any TSBs/call backs for a re-flash.

But of course technically, you just threw your power train warranty out the window with the above, as the Ford ECMs (and I'm sure other manufacturers as well) have a flash counter which tattle-tells the times the ECM was flashed/tuned, and if the dealer checks this, as they are supposed to for any engine related warranty work, and the count is too high over any re-flashes they may have done themselves as updates, you're ****** (it also is unaffected by and separate from any battery/power disconnects, so that excuse is gone as well).

So proceed down this path at your own risk.

Bought some Castrol Edge 0w-20 for this oil change this weekend. They have a promotion for a free hat so already sent that in. Will take 2 samples and send one to blackstone and to another for comparison.

Thank you all for your opinions and thoughts.

5w30 Pennzoil Platinum is what's in my 2017 Buick Regal GS 2.0T and a NAPA Platinum filter, gets the job done, no need for anything more.
