I believe but cant confirm that most of the advanced features can be turned on or off
via Mazda IDS at a Dealer, however, TPMS is a regulatory requirement for many US
states AFAIK and would not be allowed to turn off..

But yes mate, I would think a change in wheel size may give TPMS issues, but IDS does
allow to change tyre/rim size (like in S2 RX-8).

 

BTW: Looks like all the Advanced Features will be available later in GT option packages for US....

Advanced Package (late availability)- Mazda Radar Cruise Control
- Forward Obstruction Warning
- i-ELOOP
- Lane Departure Warning
- High Beam Control

 

Rough idle with MIL On with DTC P0015 / P0524

It appears Mazda are having Engine Oil Pressure issues with SA-G Engines..(MIL on P codes)..worldwide!

Symptoms, are 'stuck' Oil Pump Pressure Plunger, and or Oil Control Valve, result in Oil Pump and or OCV renewal....caused by 'foreign matter'.

Frankly, I put it down to the crap W20 weight Engine Oils used to get high mpg..not enough engine parts protection/lubriation.....ie too thin!

I wont post TSB yet.

 

Interesting. We dealt with oil pump plunger issues on the 93 626 FS engine when I was a Mazda tech. They had tremendous lifter noise and people thought they needed to change all the hydraulic lifters. A modified oil pump plunger was the remedy .

Paul.

 

thx to clueless morons who cry for "GO GREEN(ER)!" and GARBAGE politicians who will lick their shoe as long as they do what these morons said,Mazda(as well as everyone else) has no choice but to use GARBAGE oil all the time

I use 5w30 in my Sonata Hybrid, although Hyundai recommend 5w20, they also have an interesting note and said that 5w30 is also OK. Maybe Mazda should learn from Hyundai, just by looking at this site alone I see so many "f-king IDIOTS" who said I know nothing simply because "OH MAZDA RECOMMEND 5w20 ONLY! WHAT DO YOU KNOW? U THINK U KNOW BETTER THAN MAZDA?"

ok man.

oh back to SA, It's still new engine and there will be issues/problems that's waiting to be discovered, just look at Renesis. I'm not sure how SA-G oil pressure regulation works, maybe they can issue a TSB and replace some plunger and increase it somehow ? cuz now they're stuck with 5w20 (no choice) so maybe they should increase the pressure a bit see if it helps ?

 

Plunger works like every other Oil Pump M8, however none of those particular Plunger parts are sold separately, ONLY part of the Oil Pump Assembly.

Once the Dealer goes through a 'direction' matrix, he either cleans and reassembles Oil Pump Assembly (including Plunger Piston), renews Oil Control Valve, and or cleans internal part of Oil Pan...or installs brand new Oil Pump or OCV.

BTW, You were not the only one who said W20 oils were not up to scratch..

 

2.5 Litre SA Engine (mazda 6) uses same design/look Oil Pump but different Part Number.
Same OCV.
Same Oil Filter.

See SA-G 2.0l Oil Pump parts explosion below.

Parts with a STAR are not serviceable (sold)

 

Paul, I sent you 2 TSB's to your Mazdamart2 Gmail account.

 

Well, lets go about this logically for once:

If it is a lubrication related issue, that's causing "foreign matter" to plug or damage the oil pump, then we need to ask ourselves the following question:

What part is it that is wearing out prematurely, and how is it affected by the thinner oil viscosity, if it actually is at all.

Last time I checked, foreign matter doesn't just magically appear in the oil pan because you use 0W-20. So lets figure out what the material is made of, and were its coming from inside the motor.

So much for being logical about this issue.
Fly off the handle much without anything to base it on in this example?

BC.

 

The 'foreign matter' as Mazda Japan puts it is damaging the Oil Pumps (system) pressure Plunger, and this part can ONLY be replaced by renewing the Oil Pump Assembly.

As I privately said to Paul, Mazda are not know for assembling 'dirty' engine parts (block, crank, con-rods, head, etc, together) where foreign matter 'could' wash off from and into oil stream/oil pan.

IMO, this 0W20 viscosity may be 'creating' foreign matter by the many moving parts which could be prematurely wearing, perhaps insufficient protection?.

As an example, Mazda went away from Ford's Valve Lifters with washers or spacers as their adjustment, to now Mazda's hydraulic lifters, notorious for engine idle noises.
Tapper or adjuster noise has not been a customer complaint issues with Ford/Mazda MZR engines...

Also as a note SA-G engines run on particularly low Oil Pressure...IMO.

Oil pressure within specification for 2.0l SA-G:
1. at 650 rpm, 50kpa (7psi) or more
2. at 1500 rpm, 110 – 175 kpa (16.0 – 25.3 psi)
3. at 4500 rpm, 300 – 430 kpa (43.6 – 62.3 psi)

I wonder with a higher viscosity Engine Oil (like a 5W30 or 10W40) would do to engine wear/noise...although it will cause MPG to suffers slightly and OP numbers/values.

BTW, a 5W30 is OK in Europe and Australia by Mazda.

Something else I have just noticed and confirmed, but I would like Paul and BC others to have a look at this.........

As anyone can see from the Parts sketch I posted above on SA-G Oil Pump Assembly, the pressure Plunger is an actual round Steel Ball, Mazda Part Number 9961-13-000.

The age/first use of this Steel Ball goes back to 1985 and was first used at the fire wall end of Mazda Camshafts, still used today in some Mazda engines camshafts and transmissions.

This is though the first time Mazda has used a perfectly round Steel Ball as the main Oil Pressure Plunger/Piston in their engines, every other engine Oil Pump I can recall Mazda uses a small round tube shaped Piston of about 1/2 inch or less with a clean machined surface which lines the walls to seal, then a Spring under Piston and locking Pin, (also like 13B and S1 Oil Pan regulator).

These Plungers or Pistons have a very small stroke or movement range as a by pass regulator or system pressure regulator.

I am somewhat intrigued 'why' Mazda engineered the use of a perfectly round very small Steel Ball to do the same task?

 

please, I mean let's face it, you should know 5w20 created MORE problems than it solves. actually, it doesn't solve anything. MPG increased? not even measurable. but the DECREASE of engine longevity is SO obvious that no one needs no Scientific Data to back it up. (note: 5w20 vs 5w30's protection and how good they are, is available online)

 

maybe they don't want it to completely kill the oil circulation ? cuz a flat head plunger will shut everything while a Round ball (even when it's a small one) will not? Im not engineer and those stuff just came off my imaginations ...

 

Thanks Ash, got them.

Paul.

 

Well, several questions come to mind:

First off, is this "foreign matter" metallic, rubber, plastic, ferrous, or silicon in nature?

If it is metallic, is it ferrous? That would be steel, and there's few parts in the engine that are steel. That would be a direct oil pressure related, in most cases.

Is it plastic? And is it strands, fibrous? That would have me look at the chain tensioners/sliders, and the cam chains/tensioners.

Is it some other form of non-metallic substance?
Could that be the coating on the piston faces coming off, and getting into there, coating the plunger?

If its silicon, could it be another case of either too much sealer during assembly, or leftover sand from the casting process that wasn't properly washed out before assembly? I know you say that Mazda doesn't build dirty engines, but you never truly know, and they have had to rapidly increase engine production over a quicker period of time than they originally intended.

Finally, are there issues happening in the heavier weight oil markets to these plungers with foreign matter contamination? From what I remember, the oil pump volume is completely controlled by electrically operated solenoids to control the oil pressure. 5W-30 and 0W-20 are going to be similar in density/thickness at most temp ranges.

No matter what viscosity oil is used, the solenoids in the pump are going to keep the pressure at the same high/low points, so that means you lose volume with a thicker oil. Get an oil pressure gauge installed on the engine to see if there's an actual difference in pressure between 0W-20 and 5W-30 under various operating temps and loads.

BC.

 

Round ball check valves tend to allow more flow when they open a small amount in comparison to other check valve designs. More even control of pressure, as opposed to pulsing type control from the others.

U.S. spec Mazda 6. One picture shows the LED running lights unlit (or not present), while the other is shown lit.



No LED light or unlit. Not sure if the driving and fog lights are on or if it is light reflection from the photoshoot.








This clearly shows there are LED running lights present AND lit.





I assume this is the same car as both pictures were taken in LA (before or after the LA AutoShow).

 

I was wrong, thankfully . Our GT models will have LED Daytime running lamps standard with Bi Xenon HID as well.

Paul.

 

Just some unrelated Auto news (IMO not worthy of a new thread), but SUBARU UK will no longer import the Subaru Impreza or Subaru WRX STI to the motherland because of insufficient demand.

See what happens when a manufacturer walks away from Motorsport (Rallying).

I expect Australia wont be too far behind..

They will remain on-sale in North America/Japan.

 

2014 Mazda 6 Starts at $21,675

The redesigned 2014 Mazda 6 starts at $21,675

So, how does that look up against the old 6 price, PAUL??

Plus this IS a fully imported model, has a load more features and is a little larger..

Ash

 

As the article says, only $155 increase over the old model. That is really good news as the market is tough and the Altima is the leader over Accord and Camry in sales right now. Hyundai Sonata and Ford Fusion sell well too. I think all of those are built here while the 6 is obviously coming with Japan build quality .

Paul

 

Oh Yeah, and I forgot the US versions apart from the GT+ are pretty low 'spec' wise too when compared to Aussie 6 iterations...like no i-stop and no i-eloop which were not on any old 6's.
Your GT is close to $10K USD more over base 6...

 

Very nice price! I do hope the rumors of the two door AWD are true!!!

 

It's interesting that the front and rear track increase .4" with the 19" wheels.
It's sad that you can't have Bluetooth on a car with a manual transmission. My gf's Fiat 500 Sport and Abarth both have it.

Most telling, you can't get ANY of the additional safety features (Blind Spot, City Brake, Lane Departure, Forward Obstruction, Rear Cross Traffic, or Rearview Camera) if you get a Sport with a Manual. But you do get Hill Launch Assist, so that's something.

Why does Mazda hate Manual Transmission Owners so much?
What happened inside the walls at Mazda Headquarters in Japan, USA, and Australia?
