| ive searched and searched and read now the question what grease to use in a ax10 tran
Ive searched the forum through google on axials site ect and no luck. So my question is what kind of grease to use in my ax10 trans is a petrolium based grease bad for it? Should i use full synthetic grease in if so whats a good cheap one? What kind of grease do you guys all use?

ive heard petroleum based grease will soften the plastic. That being said: I use valvoline 50/50 grease. Half synthetic and half petroleum based. Used the same stuff for 4 years with zero problems. There are better rc specific greases though. Stuff that is really tacky and wont sling off

Not surprised search wasn't productive here. Much forum opinion is unfounded, and getting reliable info is pretty hard. It would be nice if someone would just post a link to a labled "plastic safe" grease. I don't have one. AFAIK most greases are petroleum based, regardless of name. Synthetic is just a different manufacturing technique for the same general chemistry. Sodium, lithium, ceramic, ptfe etc are not greases, but thickener additives in petroleum bases. IE, they turn oil into a thicker grease. Silicone greases are totally different chemistry, plastic safe, but not very good lubricants compared to petroleum products. Perhaps you can order OE grease packets from Losi, Axial, AE etc that are shipped with their kits. I figure their engineers know more about this stuff than we do. I've heard people use Associated Stealth Grease from hobby shops, but know little else about it. EDIT: Maybe this stuff? It specifically says plastic gears. http://www.amainhobbies.com/product_...ilicone-Grease Last edited by Hardline; 09-12-2012 at 12:26 PM. |

I had the same question, best is to contact manufacturers about plastic safe or run an alloy case. Upon contacting Lucas about their red 'n tacky being plastic safe, they ok'd it so I've been running it since.

| Re: ive searched and searched and read now the question what grease to use in a ax10 Guy at Mobil 1 said about the same thing. Wouldn't say a definite "yes it is plastic safe", but didn't say to not use it either. From what I gathered from that conversation, I used it in my SCX-10 transmission and axles. Rebuilt transmission recently (after over a year of use) and didn't find any plastic deterioration on the inside of the case (all metal gears). I looked specifically to see if the grease ate at the plastic. Looked fine. May be a different story on plastic gears, but I'd recommend all metal gears in transmission.

Synthetic greases dont use petrolium bases in them hence the name synthetic in it. Its all man made chemicles and are usally better that petrolium based greases. So a good synthetic is probally safest bet

I like red 'n tacky a lot. But it's definitely a petroleum grease. I use it for all my metal gears. It hangs in there. And I can buy it down the street. So not plastic safe, but hey...nothing lasts forever. Some people might get a year or more out of their tranny gears and be happy. And plastic gears are plenty cheap as long as you can get them. |

There are some rare exceptions such as certain racing oils, but I'm sure you can't even put your hands on a jug of synthetic motor oil at the local autoparts that didn't start from raw crude. | |

Are you worried about plastic gears or the plastic housing? If it's plastic gears you are worried about, I can put your fears to rest by saying, they will blow out long before the grease destroys them.

Through my experience, if I am running plastic gears I will only use a couple of drops of 50wt silicon shock oil. The shock oil will do enough to lubricate and keep things quiet. I have found that any grease used tends to make it easier to strip the gears. I am not sure if it is due to the grease eating the plastic, reduced coefficient of friction making it easier for the gears to slip, or a combination of the two. Since starting to use the shock oil, I have over a year on the plastic gears in the trans that currently resides in my 2.2s with no intentions on putting metal gears in it With metal gears its either gear science or vp star lube Last edited by Nabil; 09-12-2012 at 12:55 PM. |

Just the $10 axial steel ones. With this setup I have heard the od or ud ring and pinions skip under load

The next time I have a stock transmission, I'm going to try your shock oil trick...if it's good enough for the Champ, then it's worth a try! And Congrats on your 2.2S win |

Lubricity & viscocity are the specs the makers need to nail. The actual formula they use can vary form batch to batch or mfg to mfg. This is common in the lubricant industry. I had a customers air system self destruct because the oil manufacturer changed formulation & the new formula was a no go for his air piping. After the dust settled the mfg was found not @ fault because their product made all listed specs & they do not have to inform of formula changes. I am still waiting to decide what lube I am going with. That rock grease looks pretty good. |

I'm running Lucas Red and Tacky in all my RC's in everything from bearings, to axles and trans, even servos. These are toy cars, not F1 cars. I think many of your are overthinking it. Unless your running really high speeds, or worm gears, or desire a very stiction free drivetrain, then the Lucas is more than sufficient. The stock trans gears lasted a year before I stripped the idler. I don't believe that the failure was lubrication related. It was throttle finger related. I drilled a small hole and put a 3mm grub screw in the top of the trans case between the upper and idler gear so I can push a needle fitting of a grease gun up against it and give it a pump every once in a while. |
