hey all,
i have a 2006 mazda 3 2.3L with 100,000 miles mostly city driven for the past year or so. Been running any on sale synthetic 5w20 for the past 4 oil changes but not sure what it ran on as have only had it for 2 years. Pretty sure it had synthetic dealer oil in the past.I have not noticed any issues with 5w20 but was wondering if I should start upping it to 5w30? our winters here in canada get super cold like down to -40F sometimes so ive been running 0W20 before the winter and was planning to run 0w20 again before the winter but not sure if running 5w30 this summer will be a smart choice since ill be coming down to 0wxx for the winter anyways
Let me knwo what yall think? or just stick with the xw20 until higher mileage?
thx
