Engine break-in oil

[bsasuper]

After quite a while of being bikeless(rideable,regoed legal) I have finished a motor rebuild of my old classic 92 blade.So off I go to the shops to get some mineral oil for the first run, only to discover there aint much choice for a mineral 10-40w oil, closest I have to choose is motul 3000, was hoping to get some mobil super 4t 15-40w but mobil NZ has chosen not to sell it here?, anyone seen this in the shops?

Give Allied petroleum a call. They are the (im)mobil(e) lube agent.

I gotta ask why you need a break in oil? The days of these has long gone.

Think Joe Gibbs racing oil, main element being high zinc content. Not like you can get this here anyway...

For road application just use a good quality mineral oil and keep the first drain interval after rebuild short.

Supercheap auto Castrol GPS 4T 10w40, its an el cheapo semi that the GSXR drinks these days will do fine.
Get your gear on, start the bike, ride straight away then go for a blat over the mamaku

That's correct there is no oil called break in oil, but a good mineral oil is essential to allow the rings to bed in, even a semi synthetic can hinder the process.

Some vehicles come factory with synthetic, it is not essential at all

I always like to run new Japanese road bikes on 10W40 straight mineral for the first 6000 km too...

Mmmm, we'll have confused folks now. High zinc break-in oil is still common in some circles...

Same here, run to second OCI on mineral then onto synthetic. Works well for hard run cars, bikes, trucks and even jet skis...

Vintage vehicles use this kind of run in oil.

is suitable for use in passenger car, light commercial, competition vehicles and motorcycles. It is suitable for use for running in four stroke motorcycles with wet clutches and can be used with Petrol, LPG, E10, diesel & other conventional fuels.

Those engines will make less power and have a shorter life then.

So what are you suggesting, would you use a high zinc running in oil as a long life motor oil?

Penrite have traditionally made classic style motor oils more suitable for vintage vehicles. I have used their 20W60 oil (I got for free) in a side valve BMW motor but it was eye wateringly expensive compared to the bulk mixed fleet lube I use now days. I also did not believe (by very expensive independent testing) that their oils met the requirements of SAE only that they believed it did, but I might be wrong.

Yes they will,because I am sure the likes of BMW and Mercedes know a lot less about this than you do

Dubious....But i'm all in favour of using a straight mineral for break in on a rebuilt/rebored motor. Given the traditional cast iron liners and a chrome top ring - features common to everything up till nicasil bores became common - trying to get rings to bed using straight synthetic has frequently been a frustrating exercise.

The big manufacturers can get away with straight synthetic in new motors as they also use surface coatings which assist break in - a feature notably lacking on rebored cylinders...

kick - we both remember a certain ZZR1100 which would never bed rings due to the owner being told by his oil supplier that the top of the line synthetic race oil would be just fine to bed rings in with.......
