Engine Oil 

• 

For the rotary engine, Mazda specifies the use of mineral engine oil. If synthetic or semi-
synthetic engine oil is used for the rotary engine, carbon deposits may get accumulated 
in the intake ports and in the combustion chamber. This can cause misfire, knocking 
and/or power loss as a long-term effect. 

• 

The only semi-synthetic oil released by Mazda for use in rotary engines is ‘Mazda 
Dexelia Ultra’ engine oil with the specification ACEA A5/B5 (refer to the respective 
service information for details). 

 

NOTE:  Using other than the specified oil (especially synthetic or semi-synthetic oil) could 

result in engine damage.

Service Procedures 

Compression Test 

• 

Since the operation of the rotary engine is different to that of a reciprocating engine, a 
compression test cannot be performed using a conventional compression tester. For this 
reason, WDS (Worldwide Diagnostic System) or a special rotary engine compression 
tester (SST) in conjunction with an adapter (SST) must be used (refer to the workshop 
manual for details).
