Mazda 2.0 Skyactiv-G Engine: Problems, Reliability and Specs 

Except they're really screwing up a lot of the info. They say it was introduced in 2012 but they're not giving specs for the 2012 version of the engine. "This building is very strong" - they don't even know wtf they're saying. Trust me their grasp of the technicals is about as good as their grasp of english. That said, this is one of the very best engines on the market, in terms of efficiency and reliability, full stop.

I went the other way

Me too i am leaving my 407 for a Mazda 6

What engine oil do you use?

@@darioali5517 Whatever the manufacturer recommends

Why the hell would you buy a Peugeot… may aswell buy a Vauxhall. It’s just cheap plastic crap

I have 360,000 miles on my 2014 3 6 spd hatchback. Original clutch, no engine work needed. Last mechanic who did oil asked when I had it rebuilt. He was convinced it had a rebuild because the engine bay is so dry, nothing leaking. I've had it since 8,000 miles. It was built in Japan a few months before they started making them all in Mexico.

Would you expect those from Japan to admit they sold a crap car? Of course they claim it's great, duh

No way 5000km that is waste of money 😱 to my old mazda 3 1.6 BK I did change the oil at 20k km and it's run fine and I have 255k km on board. I have another one mazda 3 skyactiv-g and I change the oil at 15 k km

@@lauroprea1053Hi bro.. I’m from Saudi Arabia and we don’t have more mazda here , I want buying mazda 3 2.0 2024 Ist good? and Iwant Making simple engine updates for better acceleration. With the same good fuel economy. Do you have simple suggestions, such as air filter and others?

@@ba-ras the last model of mazda I think all are hybrid and they have more tehnology incorporated like deactivation of cylinder so tunning something like this🤔 I think the old one suport better modification and when I say the old one is that witth not gdi engine because they have 14:1 raport of compresion so if you"ll have a knock of the engine you"ll blow it so maybe if you want to make tunning I think it's better the old one like 2.3 engine of the mazda. Have a good day.

is it a petrol car ?

@@damian-795 yes

Good to hear. I drive 2016 6 with 173K miles and I'm still loving this car every time I drive it.

Hope mines last as long. Coming from a 2 litre 200bhp 300nm of torque, the na engine feels insanely sluggish. But once you get used to that sluggishness, the car is a joy to look at and drive

@@OG-dp1kx My 2009 Mazda 6 had 550.000 mile on the original engine and was still running when a guy ran a red light and totaled my Mazda. And you did read that right 550.000.

Best summary thank you

My 2019 (2018 model) mazda 3 with the 2.0g does average 14 km/l combined, and I go quiet hard with it.

I have Skyactive-G 2.0l 165hp in Mazda6. The engine is inferior to the Ecoboost 1.5l 165 in practically every respect. Much less torque, worse fuel economy, more engine vibrations (probably there is no balancer shaft in the 2.0l Skyactive!!!). On the highway the Skyactive is totally powerless unless one gets around 6000 rpm, then it sucks the fuel madly. So, Skyactive is a big disappointment, and a pure PR. In reality, they just make a durable turboless engine that does not stand the competition. The only advantage might be reliability, but statistically most modern engines are very reliable, especially when the car is driven on a highway at cruising speeds. It is a good engine for a grandpa who uses it to drive at 70km/h on a side road to visit his friend in the nearby village once a week. But for that one can also use Dacia or Fiat with something like 1.0l engine.

@@euregiojam You sound like someone who does not know how to drive.

@@Sn1per9CZE Go to the highway, set tempomat at 160 km/h in both cars, and you will see. No need to drive well. Mazda cut the corners with 2.0l Skyactive by not including balancer shaft. It is probably similar an engine used on some BMW car 15 years ago .Then BMW moved to turbo engines, and one can imagine it has been done for a good reason. I had a lot of discussions with Mazda customer service and they essentially admitted the engine does have unbalanced vibrations. There are many videos in RU-vid explaining basic issues with inline-4 engine balance, Mazda has a long tradition in passenger cars and is definitely aware of where the corners were cut. The story with Atkinson/Otto is essentially the same as Toyota's VVT used since decades. Higher compression ratios are possible because of regular knocking-detecting electronics present at every engine, it is all not such a big deal. Skyactive-G is a solid construction, but the marketing campaign made me expecting more. This is why I have been in general disappointed with the engine.

Only the 2.5 has balancing shaft, all 2.0 do not have it in any iteration

Hi, I'm considering getting Mazda 6 with this engine. Is it really that oil hungry? Would you recommend the car in general? Thanks

@@BennySVK117 I would definitely recommend the skyactiv Mazda 6 with the naturally aspirated (non turbo) 2.5l engine. These engines have direct injection and therefore the oil should be changed every 5,000 to 7,500 miles with full synthetic only to avoid carbon build up.

@@robbyjay8119 Thanks a lot for answer :) I can't find any used Mazda 6 with 2.5 engine, only 2.0. The 2.0 petrol in Mazda 6 2013 is bad? The used car market in EU is pretty f*cked up right now, there is not enough cars and the prices just keep going up. Since this will be my first car, I'm pretty scared to just "pull the trigger" and buy one. I want to buy something reliable, that doesn't need to be serviced every other month.

@@BennySVK117 The skyactiv 2.0l petrol (gasoline) engines are very reliable. My 2013 Mazda3 has the same engine and it has 150.000 miles on it now. However if you can find a Toyota Camry or Corolla that would be a good choice as well.

@@robbyjay8119 great, I'll try to look for those. Thank you very much for your time Robby 🙏

Nevermind, I figure it out… pcv valve

Thanks..I was checking out med websites!!

The 2.0 Skyactiv has been discontinued in the 2023 Mazda 3, I was reading. Your vehicle can only use oxygenated fuels containing no more than 10 % ethanol by volume. Damage to your vehicle may occur when ethanol exceeds this recommendation, or if the gasoline contains any methanol. Says the manual

How so? Please explain..

sure

Try a bottle of Techron Complete Fuel System Cleaner and use premium fuel (93 octane). Oh, there was another tip I saw on RU-vid about these engines. Disconnect the battery for at least 24 hours. Longer is better.

If this is "engine hesitation" that would piss off a racer, sorry, it won't get any better. If this is "engine hesitation" that a typical driver would notice, there may be something going wrong.

Is it really that slow? 😂🙈 Diesel or petrol? How much hp?

I think these can survive 8000-10000 mile interval with factory Idemitsu (or Mazda branded) oil but only if you're burning good gas in it and putting the miles on quickly. 12K is probably starting to push it, but people have sent in oil samples of this condition for testing and it was still acceptable to run. Most likely this was a mis-translation (like half of the rest of the video) because Mazda certainly does not say to run 12K mile interval.

5000 km, oil is cheap, engines are not

@cnimi agree with you the old quote "oil is cheap steel is expensive" is still relevant. Nevertheless with a 100% synthetic oil 10,000 kms could still be considered a high frequency oil change. We were doing that in the middle east and the engines were running fine. In the video it was mentioned every 12,000 miles ie 18,000 kilometers in this case I think it is risky even with a 100% synthetic oil.

Here u cant find 100%synthetic they dont name it 100% only half syn.. what are te best oli to use for the 2.0skyactive?

@@olwillow2115 Castrol makes semi-synthetic I think and Mazda recommends Castrol. Try and find some good oil for GDI gasoline direct injection engines.

Oil starting getting black at 8000-8500 km... 10000 km is a bit to long for me.

😂😂😂😂😂😂

Not all of them. It really depends on the life it lives. I drive a ‘14 CX-5 with the 2.0 and 202,000km. Fuel consumption is the same as when it was new. I have seen others that did have carbon buildup, though. All direct injection engines seem vulnerable to this.

This engine does not have carbon issues all the owners forms and research online show they Mazda has controlled the carbon buildup extremely well, especially compared to the competition. It is a direct injection engine however and that means you need to use quality gasoline and quality oil

@thetechlibrarian I will respectfully disagree with you, as a owner of a 2016 mazda 3 2.0L the valves do carbon up.

@@joshruner1348 They certainly can, same as most GDI-only systems, but not all will. It really depends on the way it’s used (warm-up/cool-down cycles), the quality of the fuel, etc.

Use oil addivites gives 0.4l / 100km less fuel consumtpion, Engine very silent ppl think its even off when theres a bit background noise.
