Thanks sir trav. I need the IP Address for the mazda media player android app.

Ive been mixing 2T oil everytime I fillup my CRDi car to avoid carbon buildup. So far so good. Is it possible to use 2T oil in our skyactiv since its a GDI engine?

I would stay away from 2stroke stuff....here's a South African study:
2-Stroke Oil In Diesel – A Technical Study
Based on the results of that study, the following conclusions were drawn:
"At a 200:1 volumetric blending ratio, 2-stroke oil has a negligible effect on diesel lubricity.
All diesel fuel sold in South Africa has to meet the SANS 342:2014 lubricity specification to ensure the proper protection of diesel fuel pumps and injector systems.
The low sulphur diesel products sold by Sasol contain lubricity improver additives which are far more effective than 2-stroke oil.
At a 200:1 volumetric blending ratio, 2-stroke oil has a negligible effect on diesel cetane number.
No measurable effect on all other regulated diesel properties was measured at a 200:1 dose of 2-stroke oil in diesel.
2-stroke oil can contain around 16ppm zinc, or higher depending on the formulation and batch.
Trace amounts of zinc in diesel are known to rapidly accelerate injector nozzle deposits.
Engine test results show that a 200:1 blend of 2-stroke oil in diesel results in a 2% loss of engine power in a 16 hour test due to injector fouling, a risk that would apply to any common rail diesel engine, but could also worsen fouling in older engines.
Vehicles fitted with a diesel particulate filter (DPF) in the exhaust system could experience reduced DPF life due to the collection of ash and metal based contaminants in the filter over time with the continued use of 2-stroke oil.
The abovementioned results should hopefully clear up many of the public misconceptions around the use of 2-stroke oil in diesel and highlight why both oil companies & engine manufacturers do not recommend the addition of any after-market additives, ie. 2-stroke oil, to the fuel tank. It is also good advice to use fuels from reputable outlets backed up by the technical support of a competent fuel company to enable the best engine performance and durability."
Thanks for the info sir trav. I heard 2T is not suitable for DPF equipt CRDi engines. My CRDI car is not equipt with DPF. 2T oil has many kinds like synthetic and mineral, JASO FB, JASO FC and etc. All synthetic 2T is not recommended for diesel engines, I use the mineral type JASO FC. Base what I read from other car forums the diesel fuel sold in our country is the lowest quality, one reason why the skyactiv D is not available here. Also the fuel additives "cleaning agent" for the injectors and etc is not present in our fuels especially euro4 fuels and that's where the 2T kicks in.
The cleaner the fuel the lesser additives, environment friendly but not friendly in engines.
Noticeable improvements no smoke, better acceleration and quieter engine.
Some of the members in that forum were using 2T for almost 8years, no problem so far according to them.
Just sharing my personal experience.

Quite wary of putting additives (its like adding more sugar to your soft drink). Tried the 2T before in my old 4JA1 but didn't notice any improvement and I thought might as well put the cost of the bottle to get more diesel fuel instead. My opinion is as long as you follow correct PMS and schedules, engines should last a long time.
I did see an episode of Wheeler Dealers (about 2 years ago) where Ed used a machine to run a can of pure cleaner through the intake manifold and clean the injectors and valves of a Jaguar. Not sure if such a machine is now widely available or for that matter locally, as he mentioned such a system was still new.
Thanks for sharing your 1st hand experience, sparcom sir.
I was just pointing concrete data from a study funded by Sasol South Africa, a company that processes fuel/chemical components and co-products.
Apart from their main products, they deliver diesel, petrol (gasoline), naphtha, kerosene (jet fuel), liquid petroleum gas (LPG), olefins, alcohols, polymers, solvents, surfactants, comonomers, ammonia, methanol, crude tar acids, sulphur, illuminating paraffin, bitumen and fuel oil.
One would think that this support alone would lead to a favorably biased 2T verdict that would work in the interest of energy companies....but conclusions drew the contrary.
Felt relief/benefits from self medication can be deceiving. That's why we see disclaimers on all those OTC supplements.
I'm aware that mind power, law of attraction & positive thinking should never be underestimated, but their effect on 2T-CRDI combo is something we have yet to see documentation.
All this is like claiming butt dyno as more truthful than a real 1. Hehe
That said, guess I'll just stay w/ factory recommendations & see how Sky fares long term. Good thing we have yojin to enjoy & exploit. Hehe.![]()
I'd trust german scientist more than south africans when it comes to engines and lubrications.
Adding 2 stroke oil to diesel tank - read this - The Brick-yard - Page 1
Why car manufacturers do not recommend 2-stroke oil
You may all know that Mercedes Benz have conducted in 2007 a long distance reliability test with a number of Mercedes E-Class 320 cdi from Paris to Beijing. Due to the fact that the diesel quality in East European Countries, Russia and China does not meet the DIN requirements, and Mercedes did not want to take the risk of their engines to flopp due to lousy fuel, the total tour has been accompanied by diesel tanks to re-fuel the E-Class cdi's. Selected members of the Mercedes clientele could apply to participate in selected parts of this test-tour, and advocates and notaries had to certify the correctness of this long term reliability test.
Although Mercedes does not like it published or made public, it is a fact that the diesel-fuel used for this test did contain 2-stroke oil to grease the high pressure pump components and to keep the engines clean during this marathon.
Why our car manufacturers do not officially allow the homeopathic addition of 2-stroke oil to the diesel fuel has many reasons, mostly of legal nature. Besides this, which car manufacturer has any interest in excessive reliability of their engines? Their repair shops will have great problems.
Meanwhile the "2-stroke-oil to diesel" issue has attracted the interest of a number of Universities in Germany, as this 2-stroke oil has shown to have amazing properties if added in a small dosis to diesel fuel (1:200), especially the positive impact on air pollution, reduced fuel consumption and improved long term reliability of the diesel engine. The pro and con discussions will go on for a while. But as soon as an academic report has been published by one of our Universities, this will change very fast.
By the way: all car manufacturers reject the addition of any fuel "additive" in their cars, and warn that guarantee MAY be affected. Nobody says, that guarantee WILL be rejected. 2-stroke oil in its properties is not an additive, as you add oil to oil if you "dope" you fuel with a dosis of 2-stroke oil. The dosis of 2-stroke oil in your diesel-fuel is very difficult to analyse, as every (chemical) analysis has the main function to identify substances which are harmful. But 2-stroke oil has proven not to be harmful at all, on the contrary!
Personally, I use 2-stroke oil now for many years in all of my diesel cars (my present business car is a Mercedes 320 cdi DPF Automatic). And I never had any problems whatsoever.
Thanks for the insights, Ry sir. Very helpful.
I hope & wish Merc would have their findings on the boon of 2T published.....
Otherwise, it would rather be pitiful, sad & disturbing to have us put more weight on unofficial conclusions vs. documented 1s based on the former being German.
Apologies for having strayed this thread way over to good diesel discussions. I'm sure there's 1 on this somewhere...
Now, back to regular M3 programming.![]()
About 60 kms of highway driving 60 to 80 kph.
I know this is not accurate but still impressive for a 2.0L
I did the full tank method last week i got 12.3km/l 80% highway 20% moderate to heavy traffic.
Mga sirs. I had the chance to test drive the mz2 v earlier this morning at mazda dagupan. I loved the rev specially in sports mode. As in zoom zoom. However, I am torn between mz3 v or mz2 R sedan. Thus, I would appreciate your opinions regarding the acceleration of mz3 v 1.5L. Is it as agile as the mz2's sports mode? TIA
