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).
