Must Read for Speed3 Owners!
By Herkdriver on
2010 Mazda Mazdaspeed3 Sport 4dr Hatchback (2.3L 4cyl Turbo 6M)
I noticed a black soot material on my tailpipes (which I've since learned is normal for turbocharged cars) but I heard that previous models had issues w/turbo smoking (smoke coming from tailpipe at idle/all engine speeds) & I thought this might be the onset. Videos are online if u Google. Mazda allegedly fixed this in 2010 but there's a "mystery" Tech Service Bulletin (TSB)for service depts to switch owners to 5W-40 synthetic vs. std 5W-30 (what the filler cap & manual says). TSB doesn't apply to 2010 models. My dealer couldn't even find the TSB in their system! Question service depts b/c Mazda N. America doesn't endorse synthetic oil or 5W- 40! Could void warranty b/c manual says 5w-30 oil.
Suggested Improvements
Mazda N. America needs to get w/it! Turbo engines need the added protection of a synthetic oil for longevity. Customers/service depts are confused by your guidance...clear it up! For 2011, chose an synthetic oil (i.e. Mobil 1) and pre-fill from the factory. As for me, I'm running Mobil 1 5W-30 Ext!
