Many BritBike threads recommend using the "cheap stuff" for breaking in new motors. Would 30w "SA" be the right stuff?

Tractor Supply Co. sells a 30w SA all-petroleum no additives.

30W would be too thin, a cheap 20W/50 with zddp would be one I would use.

Thanks, will see what's available.

How many miles to run the "break-in" oil?

For 1971 BSA A65L.

1000 miles total, change at 250,500 and 1000. Change more frequently if you want say by adding in one at 100. The main contaminant will be the ring and bore material as the rings bed in on the honing so I put a strong magnet in the sump to collect this before it returns to the oil tank or fit a full flow filter in the return line. The magnet gets furry very quickly.

i have an oil in frame.

i had a utility magnet with a hole in it from somewhere, and wired it to the mesh screen in the bottom of the tank.

i leave it there all the time.

AutoZone carries Valvoline 20W50 Motorcycle Oil. I use this on all my air cooled engines and has a nice dose of ZDDP like kommando suggests.

I think the "cheap oil" recommendation is only for breaking in a set of rings. Use that only until the rings seat, like 5-10 miles, then switch to a proper 20-50.

Maybe it's overkill, I don't know, but after spending roughly $1000 rebuilding my engine, I wanted to take every precaution possible, especially the cheap ones like three quarts of expensive oil. Someone here recommended Brad Penn 30W break-in oil, so I ordered some from Summit Racing. It was a very successful break-in, so I have to be a believer now.

I used 30w break in oil on my A65 when I switched to TS rings. It worked brilliantly. I used it for about 300-400 miles giving it a hard break in. then switched to a mineral 20/50. After 1000 miles max on the mineral I switched to semi synthetic. Bike runs a charm.

I have used 30W ND for the first 100 miles. Then I change to Mobil 1 20/50 for the next 500 or so miles and replace again. Seems to have worked for me.

I believe the API rating is the critical measure for break in oil, so read the label! Not higher than API SG.

SH or higher is too slippery for rings to seat. HTH

FWIW, I used cheap 30W (advance auto brand) on my Royal Star's last rebore (bottom end is still the original with lord knows how many miles). With a return line filter I ran that oil for about 1000 miles then replaced it with the same. This was now about four years and maybe 20000 miles ago. I switched to synthetic (mobil 1 15W-50) on my last oil change, which I'm now thinking was quite some time ago.

Thanks for the reminder since I typically change the oil and filter once a year whether it needs it or not.


BTW, I decided to use the Valvoline V-twin oil to break in my SS90 after a recent rebuild, but it didn't like it. It pretty much spit it all out on the first freeway run mad (discovered the small hydraulic return line filter I'd fitted was too restrictive, but that's another story)...

Point is, I wouldn't worry too much. If it's put together right, the bike will be fine whatever oil you use.

Thanks, for the responses.

I now plan use 20w-50 Castrol Actevo X-tra 4T

API SG
JASO MA-2

Found it at $24.99/g or $6.25/qt., "cheap" enough for me.

The only thing I found with cheap oil is a build up of sludge in the sludge trap after 3500 miles. Whilst it wasn't excessive, it would have been pretty much blocked by the time the motor had turned 20-25,000 mile.

Whether the mentally masturbating semi synthetic oil I now use from Fuchs will have that same sludge rate... Only time will tell

Oil is changed regularly in my bikes, or as regular as soon as it starts to show dirty and spin on cartridge filter changed at the same time.

What effect, if any, do any of these 'break-in' oils have on clutch operation?
My A65 breathes through the primary, so the same oil is used in there.
I know the cheap stuff won't be a problem, but what about the good stuff?

Hi David,

Aiui, either "stuff" should meet JASO MA2 spec., to avoid additives that'll make the clutch slip?

Recent post by John Healy on the subject.

Hth.

Only joking Allan, don't take anything I say seriously mate.
I just love throwing in comments like that to get a bite......


BTW SG oil has full detergent package so should get little or no sludge with a filter.

All the best
Nick


No offence taken, I found it quite funny.


RE David's quote about the break in oil effecting the clutch. It should cause no problems as I see it.

It is a much lighter oil ( wasn't the original spec SAE 30 oil? It also won't have the friction modifiers in there like many other oils have so as far as I can tell, less chance of slippage.
However, it isn't anything you want to use long term as the oil is too thin to be used for extended use.
