Hey Guys...any experience using molikote anti friction additive in Continental engines? Would it be a good choice to protect the engine during cold start? And would it be of any benefit when it comes to sticky valves? Is it OK to use it with lubricants like AeroShell W100?

I would not for a few reasons:

1-It settles out and likes to plug oil galleries, sprayers and screens.
2-It will short out spark plugs.
3-It tends to fill the hone finish of the cylinder and actually starve the rings of oil.
4-It wont stop valve sticking
5-It acts as a catalyst for galvanic corrosion

Need I go on?

No need to...you've been very graphic :-) thanx

I never found any need to use extra additives. I've used Phillips 20/50 XC in both my Cherokee when I owned it for 25 years and 1400 hours, my 65 horse Champ and my 0200 Champ with basically zero engine problems including no sticking valves. Why put something in that changes the additive package already blended into the oil? A "multi weight" (20/50 or 15/50) is a good choice for cold starting in my humble opinion.

Thanks for your words. I've been thinking about using multi viscosity oil...and I think I will try it in the next oil change for cold starts this winter.

Depending on where you live and the temps for the start I'd really try to get the engine and oil preheated. I don't have a hard & fast, but down near 45 and below I try to warm things up before cranking. I often use Aeroshell 100+ in the Summer and use a multi grade during the colder months.

I feel the exact oil make and type is only one factor in the mix. The overall care and operation of the engine with timely oil changes all contribute to longevity. JMHO.

Thanks. Here in Argentina the temperatures usually aren't too cold and the airplane is hangared...I think multigrade would do the trick. Also, my plane wasn't being flown too much before I bough it. It seems that the engine is happier now with the more continuous use...the first flights I did I had some problems with lifters and valves but the last two days were a non event concerning engine issues...

Yes, sounds warmer down there. I generally fly at least 30 minutes every two weeks, as a minimum.

This one is gonna fly much more, hopefully. My partner and I are in the process of accumulating hours for the coming licenses...

That is a nice plane mikevictor!

Thanks! It's an Aero Boero 95, 26 of them were built in Cordoba, Argentina in the 60s. Later Boero built two subsequent versions, AB115 and AB180, I think they reached 400 planes or so, most of them were exported to Brasil or sold locally in Argentina. All of them have in common a very robust structure and nice flight characteristics and were used as crop dusters and glider tow airplanes...

A few were exported to Latvia? You are in Latvia?
It looks a bit like a cross between a SuperCub and a Maule.

I am from Argentina. I am not sure about Latvia. The cockpit is roomie, like a PA12...

It does look roomy! Ok. LV is civil in Argentina for some reason I only remembered LQ.

It is roomy, indeed!

here we use LQ only for official planes and helicopters...
our registration system is very old, we reached the point in wich all the available registration numbers are used, I don't know why we hadn't changed to a more realistic system, like FAA's for instance...


go figure: 26 characters in the alphabet, 3 characters available for registration in Argentina for general aviation: 17576 planes


considering that in theory we never reuse the registration numbers, It is crazy!
