'22 Subaru Crosstrek 2.0 Mobil 1 ESP 0W-30 2.5k OCI. High oxidation??

[Glenda W.]

Your Crosstrek has direct injection and needs a GF-6A SP oil to avoid low speed pre-ignition!! Go watch motor oil geek on YouTube why you don't want to use European spec motor oil on direct injection gas engines

Did the motor oil geek recommend Pennzoil and a SpeedDiagnostix oil analysis?

He explained that high calcium in euro spec oil can cause pre ignition and damage your motor

Low speed pre-ignition is really only a problem on turbocharged direct injected engine. The Crosstrek engine isn't turbocharged, so LSPI isn't a concern.

Why do you or this geek presume that all Euro spec oil has high calcium? Are Subaru DI engines prone to pre-ignition? Why does Subaru Japan allow Euro spec 0W-30 across most of their current line-up? Even in the FB20 Crosstrek.

This is the Motor oil geek on another channel. You're incorrect he his a lubrication specialist and actually formulates oils. Please watch

They have oil that's Subaru approved and I'd use it.

That video is way to generalized, LSPI is really only a concern in a high BMEP (Brake Mean effective Pressure) engines. The most common example of that is small turbocharged engines. Naturally aspirated engines don't have high enough cylinder pressures at low engine speed for LSPI to occur especially the 2.0 in the Crosstrek. With the small turbocharged engines you get max torque, high cylinder pressures, much lower in the RPM band (1500-2000rpm) which is where LSPI occurs.

LSPI testing (aside from that performed by Mercedes) was introduced with SN+. Many Euro oils are also SP, like M1 FS 0W-40. LSPI is a potential problem for TGDI engines, not GDI ones, for reasons already explained in the thread.

Low Speed Pre-ignition Oxidation and Wear (lubrizol.com)

LSPI is an abnormal engine cycle observed at high loads and low engine speeds in turbocharged spark-ignited engines, most of the time with direct injection. LSPI involves three steps, all of which are based on a specific combustion process.
