in a car that requires 5W20! Check the top of your oil cap under your hood for verification.
you may get away with 5W30 but not 5W40---it's too thick. I still would put in 5W20 for winter, you may get away with 5W30 synthetic in the summer.
Even though it says in pdf for all mazdas, it still must be proper oil weight as in this schedule in that pdf: http://www.tds.castrol.com.au/pdf/50...98_2009_06.pdf
Castrol Magnatec Professional 5W-40 is suitable for use where the following
specifications or classifications are cited:
Where these SAE grades cited
Petrol engines, supersedes SL, SJ, SH, etc
5W-30, 5W-40, 10W-30, 10W-40, 15W-40, 20W-40
Diesel engine, supersedes CD, CC. 4WD, passenger car and LCV
5W-30, 5W-40, 10W-30, 10W-40, 15W-40, 20W-40, 30
