2010 Mazda 3 Oil Type

Are you planning to follow company manual oil type recommendation? if you are then it would be unwise for 2010 Mazda 3 models, First you have to assess engine health before deciding about the right oil type. Although company Manual standard oil type for all Mazda 3 trims are  SAE 0W-20 engine oil for 2.0 and 2.5L and use SAE 5W-30 engine oil for 2.3L engine.

Regardless of Company manual, 0W- 20 engine oil is too thin even though a fully synthetic and good engine condition might not be compatible with 2010 to 2014 onward Mazda 3 models.

All these old models driven an average about 100,000 miles or more, wear and tear of a engine does play a major part of which oil type , what brand with what technology should i have to use in Mazda 3 2010 to 2014 models? therefore first you need to consider and evaluate current car engine conditions before  deciding correct oil type.

How to evaluate car current engine conditions before 2010 Mazda 3 engine oil type use?

You don’t have to dig in detail to find out the right condition, just go through this checklist before going for next step.

  • Find out which oil was using by previous owner.
  • Check maintenance log book of a car and see any recent changes of oil viscosity and other major engine problems arises if possible.
  • Check the vehicle’s fluids. Fluids are one of the most efficient indicators of the condition of an engine. The oil should be brown, translucent and full. It should not smell burnt or be milky, clumpy or discolored.
  • Seek out leaks. Leaks are a sign that the vehicle or engine is amiss. Have a trusted mechanic examine any area of the engine you see accumulating fluid in.
  • Start the car. Car should start easily without struggling, banging or stalling. Listen to the engine run. The engine should not make any tapping, knocking or pinging noises.
  • Drive the car. Pay attention to how it accelerates, stops and maintains speed. Listen for any strange knocks, bumps or squeaks. Pay attention if the car hesitates or seems to struggle in any way.
  • Take the car to a mechanic and have a compression check performed on the engine. The compression check measures if the engine has correct pressure.
  • Check engine health condition by turn on the engine, push the throttle to 4 rpm and see if there is any white smoke coming out from exhaust, if it is then, it indicates the engine is weak and probably burning oil, or oil leaking internally. At this stage 0W-20 or 5W-30 might not be feasible for a car.

After assessing and you sure that your engine hasn’t any symptoms of weak engine, so what would be the best engine oil for my Mazda 3 2010 to 2014 models?

The best recommendation would be to continue the existing engine oil using by previous owner until unless you see signs of heating engine at high speed, burning smell coming from engine, strange knocking, pinging noises or oil burning, in that case you have to use higher viscosity grade oil and possibly oil additives as an add on to prevent from engine being damage, (these symptoms may occurs due to other reasons).

If the issues are serious then no oil with higher viscosity or oil additives can resolve engine issue, you have to go to mechanic to replace a engine part.

In addition to viscosity what oil blend would I have to use, so basically three blending oil available in the market, conventional oil, synthetic blend and fully synthetic.

Better to use fully synthetic, it contain cleaning detergents, increase optimal engine performance, increase fuel efficiency, maintain engine temperature at high speed and maintain viscosity level for more than 10000 miles, which protect engine friction and reduce engine oil cost per kilometre.

So do not afraid to buy synthetic oil if it cost more than conventional oil. Both oil cost per kilometre roughly the same, but has a huge difference of advantages using synthetic oil as compare to conventional oil.

At a stage – 1 good engine health which synthetic oil type is best for 2010 Mazda 3

You can choose from number of awarded synthetic oils.

  • Superior corrosion protection



At a stage -2 when a car shows some signs such as Burning Smell, White Smoke, Loss of Acceleration, Engine heating although all these signs except white smoke can be occurred from other reasons.

In this condition what you have to do is to change engine viscosity level, if problems still persist after changing viscosity, use oil additives, they have a specialized formulated chemical helps to heal up engine minor issues, you can use it every 20000 or 30000 miles as per effectiveness. The best oil additives you can choose from here: Most Popular and reliable Oil Additives.

You don’t have to change the whole brand only change viscosity from 5W-30 to 10W-30 SAE oil type for Mazda 3 2010.
