R3 oil usage query

Post by V8 Power » Sun Nov 10, 2019 9:17 pm

As the R3 has three oil injectors per rota compared with two for the S1 does this mean it consumes more oil as potentially 50% more flow?
Or is the same amount of oil used but spread between three injectors instead of two?

Don't have a basis for comparison, but I'd say my R3 maybe needs 500ml after 8-10 full fills (if that). Or about that much after 20 minutes of hard driving round Mallory...

The OMP rates are different. I don’t have them to hand to compare but I believe the R3 injected less as the coverage was more even in the engine.

The whole OMP system is different, with separate pumps for the centre and side oil nozzles, plus a pressure sensor providing feedback to the PCM.

The related PCM control programming is more complex than the S1, making more emphasis on engine load and less on engine revs.

This means that oil consumption may be less, or could be more, depending how you drive.

That is very interesting Dave re the different set up. Thanks for the info.
Andy
Ours is about the same 500ml per 500 miles
And as we both know Aurora blue is the best so it must be right :D

Having owned both a S1 and an R3, the R3 uses slightly less oil. But it is subjective and never actually measured exactly how much I used.

As above, the R3 uses slightly less, but then it all comes down to how you drive it etc.

AFAIK the R3 injects more oil in to the chambers on a cold start, so even if you weren't driving it hard but covered less miles per trip you may use more than someone driving it hard but over a much greater distance.

Likewise two identical R3s, over the same journey, but driven differently will consume different amounts of oil - drive it hard and you'll get through the oil quicker. I found that I could go a good 1500 miles to ~500ml when driving up and down our country's great motorway system, but on track would get through that same 500ml in no time at all - I think we all remember the CarThrottle incident... :P

Both versions also squirt oil into the chambers at shut-off, unless you've got a very early S1 that's never had the PCM firmware updated - which is done automatically if the car has even been dealer serviced.

Anyway, in theory this would also impact the overall oil consumption, per mile, if you were doing lots of short trips.
