MS3 Engine Oil Threads

[fywdyl]

I'm not saying as of now or these days my gas milage is not as good as in summer. I do understnad winter driving affect gas milage. THIS is NOT my question or concern at all.

Also, I'm NOT WORRYING about my gas milage.

The point of my post is only about Rotella T6 5W40, Is it true that it affect gas milage on our cars. Yes or no, if so, why.
Affecting my gas milage doesn't mean I'm worrying about it neither. I'm not saying I will stop using this oil cos it may or may not affecting the car's gas milage.

People jump on the judgement about why MS3 owners care about gas milege whenever there is a question about it. Again, I'm not complain the gas milage of my Mazdaspeed3.

Even if there's an effect, it's negligible:

To pass, the test oil must improve fuel economy one to two percent, depending on viscosity grade.

1%~2% on, say, a 450 km tank is only ~5 km, not 50 km.

Listen to the gurus that have "been there and done that". Many of the guys on here have been driving this car through countless winters and losing 50 km in the winter time is nothing new.

I always thought the tears in my eyes when I was filling up were from a cold wind, then I calculated my mileage...

I just fill and ignore now, lol

Thank you sir.
That is the type of answer I exepct from a car owners community.

Long time since someone has posted. Is everyone still on the rotella t6 5w-40 bandwagon?

What about a preferred oil filter?

[mickey_g]

rotella is still preferred and will be for the foreseeable future...also recommended are PP, RP, and Amsoil. Oil filter I would say Napa Gold filter, which is a rebranded WIX.

Thanks! Good to know! No change in this answer dependent on mileage right? (Or year of car?)

[mickey_g]

Nope...those oils will be fine for regular/aggressive street driving and the oil filter is highly recommended. I personally just stick with OEM filter and PP 5w-30 until the warranty runs out...

[rzapata]

@mickey_g I believe you've got a spin on oil filter correct? From what I remember, the OEM spin on filter is not designed for synthetic. Unless that's changed within a year...

There's still K&N filters (HP-1002).

Yeah the gen 2 uses a spin-on. The filter seems to be holding up fine. I did a couple of oil changes at Jimmy's and he uses OEM oil filter w/ synthetic. I mentioned that to him and he said that as long as you are changing the oil by 7K then it should be fine. Lots of debate regarding Oil/Oil filter. The Napa Gold gets my vote though. Lots of praise on that on MSF.

There's a thread on MSF comparing different types of oil filters. The guy explained how different filters have different filtering media and how effective they are. I'll post it up when I get a chance. It's good information.

Cool looking forward to it. I plan to start changing my own oil at the next oil change. I had it done at Brampton Mazda recently since I wanted to get the warranty transferred and they waved the $35 transfer fee since I was having an inspection done anyways (bought the car used). Next one up though is happening in the driveway

Just remember to put in new oil after draining the old oil. Lol

Great tip! Sticky!

"OEM" spin on oil filter is a rebadged purolator classic... why waste money on it when the same money can get you a purolator pure one, which is far better

[Pacman]

So I just called in to a Mazda dealer, and they told me I should not be putting synthetic oil in my speed3, as Mazda does not approve/recommend it. ?!

That seems weird since I was just at the Mazda dealership to change my oil and they recommended synthetic due to the kilometers on the car (it's been getting synthetic since about 80,000km).

Which dealership? :\

[TheMAN]

who cares? would you rather follow them or follow exactly what the book says and have a worn down turbo or engine by the time the warranty expires or enjoy many trouble free miles because synthetic protected your engine and turbo?

besides, NO WHERE in the manual does it says you shouldn't or can't use synthetic... it is neither approved or disapproved to use synthetic... you just need to meet the requirements stated in the manual
rotella T6 5W40 synthetic is what most people run because it's better and doesn't cause problems

LOL...go to another dealer

[Pacman]

Maybe they misunderstood me? Westowne. But they did recommend I bring In the oil and show them and have a chat.

Any West end dealer that will change my oil with rotella t6? Car is still under warranty

[Mr Wilson]

Westowne will change with whatever you bring in.....they may just mention what kind of oil it is on the bill.

I've been running T6 pretty much from the day I got the car and normally get the dealer to change it. Never had an issue.

[Pacman]

I think I'm going to go in and see what they say. Paul, do you use stock oil filters? Or do you bring in another filter? If so what do you use?

Ha, found it.

BEST OIL FILTER

If you're unsure about what filter to use, this might help you decide.

Just use oem

[captobvious75]

Just use oem

I use a mobil1 synthetic oil filter with PP 5w30. I didn't want to use Mazda's oil filter cause its the exact same one they use on their non Turbo 3s

STOCK FTW ... well because warranty
