Second oil change...

Well, it appears that the Pennzoil Platinum holds up pretty well to the turbo heat that the MS3's produce - and it appears to keep the engine's internals clean to boot.

Changed out the trannie fluid with the Redline MT 90 and what a difference it makes. The first few miles felt like the old fluid, only a little better. Then as I drove the car it seemed as though the fluid settles down (or gets mixed up, whatever) and the shifting gets better - much better. After about 20 miles I could blast through the gears with the greatest of ease.

I have noticed this same thing in my Bimmer only to a lesser degree. I can change the trans fluid with Redline MTL and in the first 10 miles or so the trannie has that characteristic BMW "pink" when you go into each gear. Then, the shifts get that cushion feeling and gear selections get really easy. The "pink" is replaced with a sort of shhh as you change gears.

While I had the car on the lift, I got to looking around and these cars are really well made, with maintaining them in mind (BMW could learn a lot from Mazda about the art of mechanicals packaging). If you drive your cars over 100k miles and beyond, this is a plus.

Little things like a removalble panel in the wheel well on the passenger side that allow easier access to the front of the engine to change the belt (my car only has one ) or the water pump, make a difference when the car begins to age. Also, it will be a breeze to bleed the clutch slave cylinder when bleeding the brakes - it's right up front and center.

One last observation before I go - when I went to loosen the wheel nuts to rotate the tires, they were barely tightened. That's kinda scary considering that just 2 weeks ago I was cruising this car out to Az and back in areas that had a 80 mph speed limit. I think I'll keep an eye on the wheel nut torque for a while to see if they loosen on their own or if they weren't tightened at the factory. Cheers all!
 
At what interval did you have your first oil change? Your second?
What made you go with Pennzoil Platinum...?

Scarey about the lug nuts... I think I'm going to check mine...
 
The first OC was at 1100 miles and the rest was done at 4300.

I chose Pennzoil Platinum because it is a Shell oil product (made by SOPUS) and is a little cheaper than Mobil 1. Price is a factor when the oil changes come every 3200 miles. Also PP has the Honda HTO-06 endorsement which is their idea of a good turbo oil.

If you'd like to find out more about oil go to www.bobistheoilguy.com a lot of neat stuff there.

Cheers!
 
Does Honda make anything with Turbos...?

That doesn't tell me much... Honda endorsing oils for turbo applications...???

I would take Nissa's (Skyline), Dodge (history of turbo use), Mazda (of course), Mitsubishi, and there are others.... But Honda...?

I'm sticking to Redline all around; engine, tranny, etc...
 
Acura has an SUV that is turbocharged - Honda is the parent company. Honda's powertrain engineers are not the type to take a half chance when they clear an engine for production - they set up a test procedure for the oil they would endorse for use in their Acura turbo and, as far as I know, only Pennzoil Platinum and Mobil 1 have it ( I can't exactly say I have researched the matter that much though).

Now Redline makes a fine oil for turbos and I doubt you will ever regret using it; however, it may or may not be validated for use in Mazda's turbo cars - they seem to real hung up on the API logo etc. Wouldn't it be a pisser to use the best oil around and then be denied a warranty claim because the superior oil you were using was not on Mazda's list of approved oils? Stranger things have happened. Having said that, if Mazda would allow extended drains on the Speed 3, I would definetly use Redline's oil - it's that good. Cheers!
 
So you are telling me that Redline turbo oil is not recommended under Mazda's list of oils...? Redline does not have the API logo...?

Thats the oil I was planning to use...
 
I have a 2008 model and the owner's manual is pretty direct about oil weight (5w30) and making sure that the oil being used has the starburst rating (API, ILSAC).

Having said that, the best way to find out is to contact Mazda and see if Redline oil is approved for use in their engines.

Redline is a small oil producer (comparitively speaking) that may not have persued getting Mazda's approval. Most, if not all, of their oil products are polyol ester based.

Speaking from my BMW experience, Redline is not on BMW's approved oil list (the last time I checked).

Would you be denied a warranty claim if it was in use when your BMW engine failed? If it wasn't specifically named on BMW's approved oil list, you may have a problem.

It's a shame too, because Redline lubricants are superior to just about anything else IMHO.

As far as the trans oil goes, in the owner's manual, Mazda merely states that lubricants for the turbo cars must be 75w90 in weight and carry the GF-4 class rating. That is all they have to say about the matter. I'm pretty confident that MT 90 would meet even the strictest warranty scrutiny by Mazda.

When in doubt contact Mazda and see what they have to say. They are an enthusiast based company so I'm sure they'll get back to you.
Cheers and let us know what they have to say should you decide to ask them.
 
In my opinion, Redline will be more than safe to use in our cars... If anything, it will protect the engine more.

The API and ILSAC logos are strictly for energy conservations, lubrication standards, etc...

A piston engine is a piston engine... Our engines have nothing special or exotic metals that need a special kind of oil... IMO, this just assures you don't use a cheap oil...

Anything used on a race car, is good enough for any street car... :)
 
Amsoil carries the logos... Maybe I'll use Redline in the drivetrain (tranny) and Amsoil in the engine...

Amsoil oil also seems a little cheaper... :)
