Some oil usage is normal. Leaks will add a lot to the usage.<br />
<br />
Don’t change the viscosity of the oil from what is written on the oil cap. The engine use the thinner oil for the variable valve timing and lift solenoids.<br />
<br />
Oil leaks can best be found by removing the propeller and cleaning suspected areas with non chlorinated brake cleaner.<br />
<br />
Once the leak has been remedied, Use a 1” brush and add a light coat of ACF corrosion inhibitors to the entire engine to keep it nice and new looking. Only add…

Once the leak has been remedied, Use a 1” brush and add a light coat of ACF corrosion inhibitors to the entire engine to keep it nice and new looking. Only add a tiny amount to the brush. Do this to the plastic and metal parts / bolts, etc.<br />
<br />
Verify engine compression during preflight with ignition off. (If not off, Engine can start)<br />
There should be 4 even pulls of compression while flipping the propeller through. Do this to verify valve adjustment is good and to see if 100LL fuel is getting into the rings (lead).<br />
<br />
The proper lead scavenger for the engine is Marvel Mystery oil. Not any additive supposedly made for this purpose. Add the oil to the fuel as described on the bottle. It will lubricate the combustion chamber just enough to prevent the lead sticking to components. That's possible.

<p>That's possible. On a recent trip I climbed to around 11k feet to get around some weather, and flew generally higher than usual for extended periods. Oil consumption was less (I was watching it) on the way back home, when I flew lower and didn't climb hard so much.</p>

<p>I've noticed a drop there as well, so will have to take another look...</p>
<p></p>
<p>On my previous engine (not a Viking) I successfully dealt with a leaky mating surface by using a product called "Honda Bond". It was referred to me by a guy who used to run a Formula 1 team. It's good stuff, and available at local Honda dealerships.</p>
<p></p>
<p>Otherwise, my Viking engine is running good. It's given me new confidence in this airplane.</p>

<p>We have a small leak which appears to be from the chain tension adjuster cover. Could not find any oil radiation from another source. Took it off once, cleaned up the mating surfaces and applied sealant. Still leaks so we need to revisit.

<p>I just got back from a 13.5 hour XC. In that time I added 3 quarts of oil. As far as I can tell, it's neither leaking oil nor burning it. I do see some spray on the ground come out of the exhaust when I start up.</p>

<p>My cruise rpm's are generally between 4650 to 4920, with most flying being at 4800 rpms. My altitudes ranged from 3500 ft to 11,000 feet, with most cruising done around 6,000 feet.</p>
