Why do engines break in mineral oil?
What Oil Type Should Be Used For Break-In. Many pilots have learned to use straight mineral oil while breaking in a new engine. It’s thought that mineral oil is less viscous (less slippery) than AD oil, and that it will allow the piston rings to wear in the cylinder walls more quickly.
What is the difference between AeroShell W100 and W100 plus?
Shell has developed a new aviation monograde which takes advantage of modern additive technology. This oil, AeroShell Oil W100 Plus, is a SAE 50 grade similar to the traditional W100 grade, but includes an anti wear additive, an anti corrosion additive and a metal passivator.
What is the type of M oil?
Phillips 66® Type M Aviation Oil is an ashless, non-dispersant, multi-grade engine oil recommended for use in aircraft piston engines where the operator prefers a mineral oil-based engine oil that does not contain dispersant additives.
How long should I run break-in oil?
We recommend using our Engine Break-In Oil for a minimum of 500-1,000 miles in street driven gasoline engines to assure that the complete ring break-in has been completed before switching to one of our full synthetic engine oils. If need be, you can use for up to 2500 miles.
What is the best oil to break-in an engine?
Use a 5w-30 or 10w-30 motor oil with an engine break-in additive (ZDDP or zinc camshaft additive), especially with flat tappet camshafts.
Can you mix W100 and W100 plus?
Aeroshell W100 is a standard Straight Grade Ashless Dispersant oil and can be used in all Continental and some Lycoming engines. Camguard is used as a corrosion inhibitor. If you have been using W100 for a long period, I would not suggest mixing them. Continue with the W100.
Can you mix Aviation oil?
“All aviation piston engine oils are compatible,” Silveira says. “Whether mineral-based, synthetic blend, straight grade, or multigrade, all aviation oils are compatible and can be mixed without harm to the engine.
What does MS mean in oil?
In 1953, the API, in cooperation with the ASTM (American Society for Testing and Materials), added a service classification system that considered the type of engine for which the oil was being blended. MS or “Most Severe” replaced Heavy Duty spark ignition engines.
Do you really need break-in oil?
Break-in oil is a critical component of an engine rebuild. It allows controlled friction in low-load areas like piston rings. Additionally, it provides exceptional protection to areas with high loads, such as the camshaft and lifters. An engine rebuild is a complex procedure that can take weeks or months to complete.
Can we mix oils from different manufacturers aviation?
The answer is yes and both types of oil are very compatible since similar base stocks are used in both types of oils.

What happens if the oil film ruptures in the cylinder?
This process actually requires some abrasion to the walls of the cylinder due to the rupturing of the oil film by the piston ring.
