Lycoming oil recommendations updated

10 Posts

For the first time in 25 years, Lycoming has just updated the oil recommendations: SI-1014N local copy

Wow, thanks @Ultranomad

What has changed, of relevant to operation?

Additional types of multigrade oils are now recommended.

Amazing, given these were around for, I am sure, more than 15 years…

However, as we did e.g. here, 15W50 is not recommended unless going down to -18C, which affects very little GA in Europe.

I am moving to 100% W80 + Camguard now.

Why? To me the artical very much seems to recommend a multigrade oil.

I wonder if continental’s recommendations would be any different?

Sae 40 is recommended for 0 Celsius to 32 Celsius however 15w50 or 20w50 works for -18 up to 32 which works fine for most of europe i’d say…

There are issues with multigrade and degraded oil seals – as well as a general increase in oil leaks all over the engine.

Mmh… “fixing” an oil leak by simply using thicker oil is not really a fix, isn’t it ? :)

There’s always a religion about the oil people use.. in Florida or very warm places on the planet I agree for not using Multigrade oil however in Europe, where you really have like +35 one day and +10 the next day over -5 a week later IMHO Multigrade does make sense…

If you have a preheater and and outlet available however it’s a different story … ;)

SAE 40 single grade ashless dispersant oils are recommended from –18°C to +32°C (at least). My club (at 60°N) uses such oils – e.g. Aeroshell W80, Total AERO XPD 80 – exclusively. (Except during engine break-in of course.) Temperatures below –18°C are seen only once or twice a year and we are using engine preheat anyway whenever the average temperature is below +10°C. It works very well. We fly ≈1100 hrs/year with four aircraft and have not seen any oil-related problems.
