2010 Mazda 3 s Grand Touring 4dr Hatchback (2.5L 4cyl 5A)
I have had nothing but great driving experiences and initially when this car came out people were wineing about the front end ,now almost every car company has stolen the body of the Mazda 3 2010 hatchback .people are stopping me at gas stations so it seems mazda again way ahead of its time .I'm writing this just after the first plug change & using mobil1 20-50 syn as factory oil in 2010 for the 2.5 was 20-50 Dino , I switched after break in at 10k .
Then in 2011 the 2.5 got 0-20 syn as factory oil.
So after plug change this thing bloomed like a new car and
rips like a rocket that's been sport tuned . It definitely still blueprint
This engine is amazing at 65k and ridiculous oil changes every 2-3k after a 5k first oil change for good break in followed by another 5k of Dino oil , then a switch to Mobil 1 and 2-3k changes thereafter . Granted I don't drive it hard , but I have been in some traffic jams and that sitting is hard on any engine , also i change the Trans fluid every 25 k.
As theres no service advisement except see dealer ? If you can find a mechanic you can trust or just do it regularly ,I choose to be safe as changing Trans fluid as it's a big overlooked service on an auto Trans . And this electronic Trans is killer and if you got one of the first 500 2010s shipped to the states you got a Trans cooler also
The Trans cooler , can be easily spotted by looking directly at the front of the car at.
About 2 ft up and you will see the drivers side black vent is actually webbed and allowes air to pass thru it and open the hood and down below the headlight assembly us a small 5" x 10" small radiator tucked neatly in there .
Guess Mazda found they just put to many things on this car initially as in the USA in the 2 quarter they eliminated the side mirror integrated turn signals that are mandatory on all cars in Europe . But not the US , so 86 . If you
got an early one like I did you got both of those items ,no extra .Needs temp gauge instead of idiot light ,and no oem gauge is offered aftermkt.grrrr
