Blood For Your New Engine

[Simon-S14]

lol. with cheap oil, it still lubricates yet still allowes the rings to wear and bed in, which is what you want! otherwise you're never going to get a good bedded in engine. So no its not an old wives tale.

If you do some research into engine oil

i deal with oil companies everyday. i know exactly what works and what doesnt..... and who promotes bullshit and who doesnt.

I worked in a oil laboratory for several years - so I know oils.

Eveyone has their own opinion - but I wouldnt use recyled oil ( all cheap oil is recyled ) in a new big dollar engine.

I used penrite-running in oil as I wasn't keen on cheapo bilo oil and since have run motul 8100 5w40. Its a 'true' grp 4 base stock synthetic.

Sure the castrol oils may work ok but if I pay good $$ for a full synthetic oil I expect a full synthetic oil.

Not to be ripped off with some grp 3 base stock that is claimed to be 'almost' as good as a grp 4 base stock synthetic.

Motul; you really cannot go wrong.

Spoolup; what run-in oil would you suggest? I did consider using the plain old castrol gtx that doesn't have non-friction modifiers..

The penrite running in oil I used is most likely recycled oil also but it was $28 for 5ltrs so not super cheap.

Mines still running well; travelled 60,000km's with forged pistons, king bimetal's and still compression tests the same as it did after run in.

Still doesn't use a drop of oil and oil pressure it good.

5 DOLLAR CRAP for 500kays. and abit of boost abit of revs and no ideling or cruising

hi,

why do you say "no ideling or cruising"? i thought the opposite -- that i have to be tender with a new engine. I will have the "first start" in a week or two. I thought that it will be good for the engine to idle for a few hours and after that -- to cruise off-boost for a few hours.

[Cubes]

Its well known never to be tender with a new motor.

Lots of load in bursts; different amounts of load and at different rpm's. I drove mine along the seafront with lots of round abouts so lots of slowing down with hard acceleration. I disconnected my turbo's actuator so I could give it some up to 4000rpm without it instantly pushing 11-12psi.

Ive found a good grade mineral or semi-synth oil is best as you still need the oil to give protection as proper engine run-in requires that you load the engine up ie up hil high gear low revs which loads up the bearings

[Cubes]

Nothing to do with 'loading up the bearings'.... More so to bed the rings in so to speak.

Running in is an old wives tale. Build motor, put it the best synthetic oil you got and go thrash the guts out of her! Thats what we do and no worries mate
