 |

Just to help confuse matters we have been using Phillips XC25/60 Radial Engine oil in both our M14P and Housai for over two years and 1000hrs. We have ADC oil filters and have never seen anything but very small particles and carbon which have diminished over time. We also do an oil analysis at every change and have watched the particulates decline each and every time. This was not the case with AeroShell, probably because of the hard starts in cold weather and the long wait for the pressure to come up.
We also run electric pre-oilers and they would have a hard time pumping the cold AeroShell through the engine. We see the oil pressure come up when using the Phillips in less then five seconds every time.
If you are making metal you can rest assured it is NOT the oil you are using. We have spoken at length with Phillips oil engineers and that is when we decided to change from Shell to Phillips. The Phillips oil performs better in every respect as it was specifically designed for radial engines of all types. Anyone telling you otherwise is just spreading BS. Also of note was Phillips (as well as AeroShell) caution to never add anything to their oils, ie: Marvel Mystery, etc. It only degrades the oils ability to protect your engine. As the Phillips engineer stated "why would we spend millions of dollars developing a new modern oil and leave something out?"
Our engines of course start much much better when the weather is cold, and the oil pressure comes up almost instantly, which as stated earlier by another Yaklister is where almost all major wear starts.
Our advice is to not take all these old wives tales to heart and to seek out the real data and compare it, then make a decision based on that.
Happy Flying!!

"WHY" the Engineer asks? Corporate BS perhaps. Bean-counters and marketing have cheapened many good products over the years. Gotta leave room for next year's "new and improved".
I'm not taking issue with the Phillips Multi-weight Radial oil because I don't use it. I stick with what I was told at an OSH WB forum by a guy from Pacific Airmotive that re-builds the old radials. "Use single weight oils". That being said, all through WW-II, smart crew chiefs added MMO to get better results under military operating conditions.
Cold weather starts are a real bitch here in Florida, I often have to wear my heavyweight shorts and Tee shirts due to the extreme cold on my bare skin.
Another tip from these forums, DO NOT use automotive oils, they contain zinc and sulfate compounds for better wear. These components leach away the thin Lead coating on the master rod that is Silver plated. Once these compounds hit the silver, the plating goes Tango Uniform and an engine seizure occurs.
All depends, I guess. Operating procedures may be the biggest variable.
