Hi, was wondering about the magnetic oil drain plugs saying it attracts and "filters" metal bits in either the oil or transmission tanks whichever one you use it on, anyone have any of these products and see any good in it? What brand/price? Thanks. |

It will probably be more effective (if at all) to wrap a strong magnet around the oil filter instead, since ALL oil goes through there. Drain plug has too little surface area to attract any metal bits. |

The magnetic plugs actually work to properly align ions in the oils and make for better flow and cooling.
True story. |

Well, I bought one anyways, for 9 dollars shipping included. Some other guy on eBay was charging 16 for a Japan-made one but was charging 9 dollars shipping and he lives like 2 cities away from me and wouldn't let me pick it up  |

I run a magnetic oil drain plug on my car, I also have some strong hard drive magnets stuck to my oil filter. Who knows if it makes a difference lol |

Haha, where did you hear that from? Oils ain't ionic or else they'd dissolve in water. Or at least that's what I learnt in year 11 chemistry.
Jonathan, let us know how much crap is stuck to it at oil change. I think I've got a magnetic filter in at the moment. I might rip it apart when done with it to see if anything is stuck to it. |

I'll have you know i work on Castrol's lead research team for their sports market and we have been trying to develop an oil which has microscopic magnets already in the fluid so that you do not need to do this sort of thing. |

The reason for that be so that when the car sits idle for a while, the oil is not fully drained down to the sump. So there is still oil all around the engine on start up, the oil would cling onto the pistons or whatever, preventing wear. Most engine wear occurs on start up  |

That's a smart idea for the micro magnets in the oil, however I probably won't find out how the magnetic oil plug works until the next oil change since I'm putting the new plug in tomorrow. |

If oil was truly magnetic, it would stic to the insides of the block, the under section of pistons, on the side of conrods, and all the other areas where moving parts will never meet and make contact with, meanwhile the moving parts dont have as much clean fresh and cool oil passing over them.
Also, when it comes oil change time, the bloody oil wouldn't drain to easily, because it would magnatise and stick to the insides of the damn motor...
I will stick to normal oil.
Also, for those that dont know, in the Auto Transmission, there are 3 extreamly strong magnets in the sump tray (seen from the outside with 3 flat 2cm x 3cm sections in a triangle), and I haven't taken the sump off the engine, but I have seen similar flat sections as well, so I am assuming there is magnets there.
When doing my gearbox Solenoids, there wasn't a huge amount of metal on the magnets, but there was some there, so they do work.

The oil we are working on is designed for primarily alloy engines which so far in testing have not shown your typical magnetic traits when working under normal temperatures and flow rates.
PM me if you would like me to keep you updated with how we are travelling. |

Can someone confirm the thread diameter of an oil plug, 12mm x 1.25mm? |

Callum how is it any good to have magnetic oil in ally motors as the ally is non magnetic. and yes i realise that some alloys can be magnetic the ones used for motor building are not |

So we have alloy cams,cranks,oil pumps,valves,piston rings,gudgen pins,etc ?
Try this ,get a magnet from an old hard drive stick it on your oil filter when its time to change it cut open and have a look at what the magnet has caught . |

Whilst the heads and crankcase are alloy, every part inside that is subject to wear is steel.
The steel piston rings run up and down inside a steel bore liner. Steel cams run on steel followers and push on steel valves. Steel crank and steel rods etc. |

My mate bought one of these... Stupid •••• quality. Keep your original one with you you will need it next time you try and tighten it. Wasnt strong enough to hold pressure on the sump plug washer, leaked and when he tried to nip it up the threaded section broke and the head and magnet fell out.. Dropping his brand new motul oil out. In the middle of nowhere, no spare oil, no plug and thread stuck in the sump. Sounds fun at 2am 50kms from anywhere. Id stick to a strong magnet on the sump. I have an old hard drive magnet on mine. When do a change you pull it off as the oil starts draining and takes most of it with it as drains. Ive been looking for some for the filter aswell i cant remember who made it and wasnt able to find any so stuck another magnet on it lol |

the lsd diff i recently swapped has a magnetic sump plug, i can't guarantee its a genuine original part. i do under stand the benefits of the magnet attracting metal particles that will occur during the wear process.
but i think they're more for a systems that dont have a frequent service interval. ie you dont change your diff oil every 5000k's as you do your engine oil so "most" particles will be drained rather then keeping on circulating. so having a magnet to trap what ever it can to keep out of the oil film/wedge will be a positive during a long life cycle.
so yeah i can understand them on a transmission setup but not really on engine oils that see frequent changes in oil |

Shane ,prove me wrong !  stick a h/drive magnet on your filter ,cut it open after 5000ks ..you will see a milky silver area were the magnet was. |

The diff ones are genuine. You are correct about longevity wit oils but also gearbox/diffs will create larger particles so need to get them out of the oil as would wear out bearings and surfaces and teeth. The magnets do help in engine oils but the filter replacement interval is alot less than driveline oils. So does get taken out more often but if you have a magnet there it wont do any damage to stick it to the filter/sump. Its basically like having a better filter for your air intake.. The more stuff you remove from the air the less chance of damage. |

Also remember many steels are not particularly magnetic - some not at all - often the alloy compound reduces the amount of free electrons dramatically. |

magnets on the sump are a bad BAD idea
I have seen the results of what happens if the magnets come off and its not pretty |

Cheers Gary, sure has raised a bit of interest ;).
So if magnets on the sump are a bad idea, and the magnetic plugs a prone to snapping, would a magnet on the oil filter be the best bet, or, no magnets at all? |

This was from a rooted diff. When I pulled the back cover off there were bits of gear teeth everywhere. The plug only held onto the smallest bits and shavings. |

Diffs and manual gearbox's have had magnetic sump plugs since at least the early 80's.
Auto box's have had magnets in the pan also since the early 80's.
But engines never have...
Food for thought. |
