Default Air filter oil/ spur gear issue

Hey guys I am new to R/C nitros, I have a savage 4.6 and I just cleaned the air filter. Do I put the air filter oil on right now or do I put it on right before I run my car. I will not be running for a couple days so I wasn't sure if the oil had to be put on right before running or if it even matters. Newbie question I know :/
Also I have gone through 3 spur gears in like a week. What is the best solution to this problem.

It won't hurt to oil the filters before hand, days, week or longer, as long as they are oiled right through but not to much. You can buy them pre oiled so it can't be a problem.
Make sure the spur gear & clutch bell are aligned straight & not to little or to much play between them.

The only air filter oil I ever had a problem with was the orange goo sold under the RB brand. It does not wash out and it slowly melts the foam. All other experiences have left me with the belief you can pre oil all you want.

I've never used any proper rc filter oil, I only ever use car engine oil, atm its Valvaline 20w/50, never had a problem & never had any damage to filters.
Its cheap to.

I use Bel-Ray motorcycle air filter oil for foam filters, you can in qt size and will last for years. I use one of my shock oil bottles for my air filter oil and fits perfect in my tool box. I coat both filters main filter and pre-filter.

As for your spur gear, like one of other guys said check your gear mesh. To much gap and the teeth are gone. Cut a piece of paper about 4''x1/4' fold in half so you have 2 layers of paper. put it between the spur gear and c/bell tighten your motor down. this will give enough gap between your c/b and spur. It should tell you in your manual about proper clearance for your spur.

if your spur is plastic then you will ruin them all day long with the savage. buy the alloy version and buy the HD mod1 drive gear for the gear box, This way, you can run the slipper tight an not have to worry about anything

Ahh getting extremely frustrated!! I re did the mesh last night with the paper trick and moved the motor over. I ran the truck for less than 10 seconds and the spur gear went out again. :/ think that's my 4th or 5th one this week.

Took it to my LHS today and my mesh was too loose. I used the paper trick but I guess I was still to loose. The guy showed me what the play in it should feel like and I think I got it down now. Just got done running and I got through 4 tanks with no problems.
