At least if you do have overconsumption of oil, you can continually add oil and not have the engine self-destruct! I'd call this Supra problem WAY more benign...

It’s less than 1% not 8%. Roughly around 16,000 987.1 caymans were sold. 1% of 16000 is 160 cars. So yeah, exaggerated.

B58 motors acceptance level for oil consumption is 1qt for every 1000 miles. Which a lot of these Supras are well within the limit. There has been only two Supras that I know of that has gotten an engine replacement.

That being said, oil consumption is over exaggerated.

My guess is the oil control ring/rings are to weak. Subaru has this problem in many of their engines because they want to run the thin oil while having as little as friction as possible to maximize MPG! They went so far as to replace the rings with different ones after 2015 in Legacy models and others...still have our issues especially if downshifting during spirited driving.

This isn't a Subaru engine so not even remotely relevant.

Was somewhat more of a 986/996 problem much more so than 987.1/997.1. Earlier dual-row bearings and later bigger 9x7.1 single-row bearings had a lower failure rate. 2001-2005 according to my sources had the highest failure rates, reportedly on the order of 8-10%.

Add to the IMS failures D-chunk, bore-scoring, and poor oiling (one of our own lost his 987.1 Cayman S to this), those engines were kinda garbage...

Different league of problem levels vs. 1qt/1000 mile oil consumption.

The Supra does not have consumption oil issues. Normal operation.

That was kind of my point from the time you said "overblown, just like IMS failures".

No, engines consuming a bit of oil is not at all comparable to IMS bearings disintegrating and destroying engines...

i believe you own a 2020 and so far those aren't the ones with the issues.

Okay as one of the few on this board as an ACTUAL mechanic and an ACTUAL machinist..




1) OEMs claim the 1qt oil burned everyone 1000miles and as a way to protect themselves from lawsuits. Ever hear of the legendary 22RE motor or quite frankly any older toyota engine. Fucker could have 300,000miles and not burn that much...but a brand new ford explor


2) If Subaru had oil control ring problems because they were not strong enough resistance due to them trying to reduce friction to hit higher MPG , you really think another OEM didn't fuck that up either??

I think it's pretty cool!
