I thought this was the norm for a break in?

I asked op if it was a being used as a run in oil..... He didn't answer that.

Yes i'd use Dino for the first 1000 Km for run in.

Aha, no idea here but reading his car build post I was under the impression this might be the case. Then again I am no expert on these things :P...

u dont run full synthetic until atleast 10,000kms.. My built 2.5 engine has only done 3k max, so need to use a mineral oil until then.

If i could go with another oil it would be motul..

And u cant compare a race engine to an everyday engine... its like me saying that i should increase my rpm to 12,000 because formula 1 engines can do it....

19k limited now since beginning of last season ....

You miss my point entirely..... No shit that f1 spin to 19k.

My point is that if mobil1 can protect the most highly strung/stressed engines on the planet (F1) then running it in an EJ is a non issue.

Using Porsche as an example (because I know them inside out- it's my job).
All Porsche cars from 1960 onwards use mobil1 5w-50. That covers engines from 30hp air cooled 356's all the way through to the 400kw twin turbo 911 Gt2.

I don't consider a 30 hp 356 motor a 'performance' engine, but a turbo 911 or gt2 absolutely is.....completely different technology between those two extremes, Yet they run exactly the same oil.....Go figure!

Why 10,000 Km before switching over? 1000 Km I understand as it allows the rings to bed propery and prevents bore glazing.
What's the benefit of 10,000 km on mineral oil?

The explanation that full synthetic isnt good, but a semi-semi synthetic is a better option...

This was an explanation by micheal south...

"EJ's have a large bore, thin rings, and very low tension to reduce ring drag with there large bores, this reduces fuel consumption, but it can lead to bore glazing when using full syn oils.

You will find that a lot of new engine designs will be heading this way, just with ej's bore been so much bigger they have to run a lot less tension as larger bore makes for more ring drag, makes more friction, uses more fuel."

here is the thread:

O.k. but Porsche uses a larger bore (100 mm in the 996 -> on turbo, Gt2 and Gt3 along with 1 & 2 mm thick low tension ductile rings), they literally never wear bores! (although cracking isn't common, it ocassionaly happens due to the open deck block design)

I'm yet to see one with glazed bores either, they run Mobil1 from the very first start.

I have a Piston on my desk out of Paul Summers 997 Gt3 RS (the Green/black one) that has done 2 x Targa west, 1 x Targa over east and 2 x duttons + numerous track days (engine lunched due to aftermarket Cat disintergrating and engine exhaust scavenging strong enough to pull bits of cat back into the combustion chamber through the exhaust valves, destroying the exhaust valves & seats!!).

The piston has no measurable wear, the skirts are teflon coated and are unmarked - the crowns are spotless (can still read laser etched batch # and sizing).

Bores were still cross hatched after a hard (race only) 25,000 km!

Oil is like Burbon......You drink Jacks - I drink Cougar.

My last 3 Scoobs have been on either Mobil1(5w-50) or Castrol Edge (10w-60), None were using oil between services (every 5000km).

Current STI has 190,000 km on it's original block, I use mobil1 5w-50 as I said before and even this well used motor doesn't use enough oil to warrant a top up between 5000km changes.

I'd be suprised if it were possible to glaze a 'big build' Ej anyway and the fuel flow of the run in tune alone would be washing the cylinder walls assisting the ring bed in, perhaps if you doddled around at light load or in stop /start traffic there may be a chance....albeit a slim one.

I wouldn't be suprised if rally cars glazed bores ocasionally, 32mm restrictor, wild-ish cams and all that.
