Whilst working in the US I used Marvel oil as an afterrun. It was very effective and I have not had to change any rear bearings for some time. Now I am back in the UK I do not seem to be able to buy the stuff. Any good alternatives?


Thanks

Nigel

3in1 or WD40 work well as anti corrosion after-run oils

but you don't want to put WD40 in an engine if you haven't put it in from the start of the engines life....

any rust that might have formed in the engine will be 'moved' when you use WD40 and will shag the engine....!

There have been similar discussions here before, try a search for WD40.

WD40 will remove existing corosion and form a gum if used for long term storage unless you ensure that the engine is semi-sealed..

However, the question was about after run, not long term storage...

Iron oxide (rust) isnt harmful to the engine, but the combination "gum" from the mixture of the different oils, combustion by products, and the rust "powder" can cause problems if left for a good few months...

All my engines are hydrolocked from day 1 with WD40 to facilitate crank nut tightening.. guess thats why I havent had any problems...

NovaRossi after run oil. Should be available from shops selling nitro cars and engines.

Neither 3 in 1 nor WD-40 is a suitable after run oil - period. WS-40 evaporates very quickly leaving little or no lubricant on parts and 3 in 1 does not chase water vapor out of the engines and was not designed to do so.
Sure you can get away with using either one but why risk it unless ou have $$ to burn rebuilding engines sooner than later.

If you cant find Marvel Mystery Oil or its much much better cousin Marvel Air Tool Oil then you can use a gun oil but even better would be some brand of Air Tool Oil. Most modern auto repair garages use air tools and insert this type of oil into their air system and tools to lube and chase out water vapor which is the culprit in both air tools and glow engines. Air Tool Oil is also possibly the best long term storage oil for glow engines as well.

If need be I can mail you a quart of Marvel Air Tool Oil if you send $$ first. They also sell a 4 ounce squeeze bottle of it as well for around $2.50 but I don't know how much mailing to the UK would be. $3-5 maybe? Its good stuff but you should be able to find air tool oil where you live unless the Queen has cornered the market on it.

Haven't had a problem in twenty years of modeling... Not wrecked an engine yet and that include .21's from when I raced in the british national 1/8th series...

Thats coz the WD40 displaces the moisture which causes the corriosion, once its done that doesnt matter that it evaporates..

and 3 in 1 doesnt chase the water, it just coats the metal so the water cant get near it..

can you just explain how that can do more harm than good.. yes its not as good as MMO but its available and cheap..

My remarks are based upon expert advice from reading Clarence Lee's columns and the late George Aldrich's advice from the old and long defunct RCO. Both these men knew more about glow engines
than most other people and I never went wrong heeding their advice. They both specifically recommended not using 3 in 1 or WD-40 for after run oil. Thta was god enough for me and many others as well.

I haven't had a car accidentin many years but that doesn't mean I don't have insurance.

Did they recommend it above nothing?

My point is, yes its not as good as MMO but is it better than nothing or other alternatives???

I just checked some of my boxed up engines that have been part filled with WD40 and the piston positioned at TDC...

The only problem I can see is the O-Ring is perished (usual with petroleum based products on this type of rubber), but the engines are fine and clean with no rust, gum or other nastiness... and there is still a lot of WD40 in them...

I wonder if the warning was mostly about the rubber/oil reaction???

I think WD-40 may be sold here in a form different from which you in Blighty must have. I have ony seen it here in aerosol form. Do you have it in a pourable liquid form??

i've only seen aerosol form here, and have been told numerous times by numerous names in the business here NEVER to use WD40 in engines.

Then you need to come back to the United States, huh Nigel?
