Changing Type of Oil Used

[Cruiser]

Maybe I'm missing something or don't understand your question... Not sure I understand how Camguard has anything to do with starter issues?

The continentals use a different starter setup than the Lycomings. There is a starter adapter and the starter that are exposed to the internal engine oil. I suspect Gregg is referring to the lubrication qualities of Camguard causing the starter to slip.

Thanks for the clarification... Got Lycoming on the brain!

Having used exclusively Aeroshell 15W50 + Camguard, will there be any noticeable differences after I switch to Phillips X/C 20W50...i.e. engine temperatures, oil consumption, etc??

 

Any personal observations from those who have made this particular switch would be most appreciated!

Well, one anecdata point:

 

Long story, but I had an oil change done away from home after 20 hours (just bought it). They put in 100W. My oil consumption per hour went up "a lot". I wasn't keeping track (I know, but I'm a new owner, didn't know any better) so I don't know how much, but it did go up noticeably. A few months ago, I did my first oil change and put X/C 20W50 back in there (it's what Wilmar recommended), and my oil consumption is back down to 1 qt every 8 hours or so.

 

I remember reading an article about how some airplanes are just "happier" with a certain oil. I have no idea why, or if this will happen for you, but I thought it was interesting.

I've been watching Mike Busch's "All About Oil" webinar.  From what I'm understanding, non-synthetic (better for cleaning) & mono-grade (better for sticking to the cam) is the way to go, unless you're anticipating a cold start...then use non-synthetic multi-grade Phillips X/C 20W50.  He states that the major portions of engine wear occur in the first 20-30 seconds following the start after the engine has sat for awhile and the oil has returned to the pan.  He also states that engines don't "wear out" they corrode from the inside out...cam lobes, lifter faces, etc.

 

So, W100 for the warmer months and Phillips X/C 20W50 for the colder months, right?  

 

Well, here's my question...

 

I want cold start protection (the way I see it the engine has sat for a few weeks in warm or cold weather OR cold weather unheated starts) and corrosion protection, right?  I believe the "runny liquid" Phillips X/C 20W50 is going to re-lube my engine's innards quicker after the engine start than the thick W100 will, which IMHO is going to decrease engine wear due to engine starts.  And, I'm always going to to use Camguard to help fight corrosion.  So, why wouldn't I want to run with Phillips X/C 20W50 + Camguard year-round --- better protection for engine start wear, cleaner running engine (non-synthetic) and corrosion protection from the Camguard?

 

It just seems to me that the W100 is better at corrosion protection because it's heavy & sticky, but once the engine has dripped dry on the inside, it seems to me that it would not be the best choice at protecting one from engine start wear...again, assuming the engine has sat for awhile like mine generally does...

 

Thoughts / ideas / Opinions?

Simple: Phillips X/C 20W50 year round.

 

Camguard makes a great product. Umm.....reminds me of a pilots rule of thumb for airplane engines and women:

 

"If you're not sure then an extra layer of protection will prevent future ailments".

Ok.. OK. FINE.

 

Damn.

 

I'll try camguard.
