Hello all. Is it true that people join forums after they've just bought an item that the forum discusses? Hmmm, guess what I bought today. 2010 M6i GT with Tech and Navigation packages. But I'm not new to Mazdas. Two years ago I bought a '06 6s and a '07 6i. My oldest son got the 6s as a college grad gift and I kept the 07. Well, today my other son got my 07 and I picked up the loaded GT. I'm having lots of fun reading the manuals to all these features and was wondering which ones I should keep an eye on for possible problems. I do auto detailing as a hobby and am looking forward to bringing the best out of the Dark Cherry Metallic finish. Pictures to follow.

 

I know the 6S has poor exhaust flow. See: https://www.mazdaforum.com/forum/maz...-design-28940/

Make sure you change all PCV valves in your cars as Mazda never changes them or inspects them!

 

Thanks UYN for the tips. On the PCV issue. Is that a policy with Mazda, or just your experience? So, if I take it in to get a tune up and specifically ask them to check the valve, they won't?

 

It's not on there Service Schedule (attached). I folded it up so you could see it better.

Best time to do it is when you change your spark plugs (if you haven't already, you are due).

Neither is tranny fluid on schedule to change. Do not be fooled with lifetime fluids. READ: http://autos.yahoo.com/maintain/repa...ques123_0.html
Some hi-lights: every 20 degree increase in operating temperature above 175 degrees F. cuts the life of the fluid in half!
At 195 degrees F., for instance, fluid life is reduced to 50,000 miles. At 220 degrees, which is commonly encountered in many transmissions, the fluid is only good for about 25,000 miles.
According to the Automatic Transmission Rebuilders Association, 90% of ALL transmission failures are caused by overheating.
On most vehicles, the automatic transmission fluid is cooled by a small heat exchanger inside the bottom or end tank of the radiator. Hot ATF from the transmission circulates through a short loop of pipe and is thus "cooled." Cooling is a relative term here, however, because the radiator itself may be running at anywhere from 180 to 220 degrees F.!
I recommend an external cooler for automatic transmissions (especially on front wheel drive where everything is close by with under hood temps being fairly high).

Ok, I'll make sure those things are taken care of. As far as plugs go, I think I went with Bosch Iridiums on my last two mazdas and they've been fine. Does the 2010 2.5L engine call for the same? I've already ordered the K&N, Rain-X Lattitude blades, and carbon-activated cabin air filter, which are standard immediate replacements for new vehicles I get.

 

Not sure. Mazdas OE were NGK's before. NGK's are good. I recently put NGK iridiums on as they are a little thicker tip than the Denso. Product Features: 0.6 mm iridium-tip. The Denso I had were only .4 mm tip.

Ok, I thought I'd take your advice and I ordered the NGK Iridiums. Now, my next question is oil. I have a show-car quality fully modded 1994 Mustang GT supercharged which I purchased in 1998 (still has 38k original miles) and have always used Mobil One filters and oil on it and it has never left me down. But recently, I've read that Amsoil full synth is the best oil money can buy. I see you use Lucas ( I actually use Lucas UCL in all my cars--I buy it by the gallon). What are yours and the community's at large opinions on this? On the subject of tranny coolers, I couldn't agree more with you as I installed a slimline tranny cooler on my mustang which I attached to the front of my radiator and it works very well. I also use Redline's Water-wetter in my coolant and it works like magic. Any thoughts? I hear Royal Purple oil and Pennzoil are good too.

 

I didn't have much praise for Royal Purple. I was starting to use oil when I had it and changed my PCV valve (don't know if it was related issue). I also decided to switch to Amsoil: it was very good but really expensive and I don't do enough driving to warrant that expense but I did want synthetic. I am impressed with the Lucas oil so far since I put it in back in November. I use Redline's water wetter as well!
Did you enter the contest for the 2013 Supercharged Mustang? If you win it, you could give me your 1994!

 

My stang would blow the doors off that 2013. In fact, it could probably beat most Shelby GT500s. Mine is dyno-ed at over 540 hp and does 11.8s in the 1/4 without nitrous. And the SN95 stangs where absolute bloated heavy cars at over 3700 # curbside weight. My stang also has a Sony custom sound system and air-conditioning with all the other power options. Just think about its speed if it was gutted out for racing. I put in over 50 modifications on that beast and it's still luxurious enough to take my wife to dinner in. The only problem is, that I never drive it. I keep it in the garage and have Classic plates and Insurance for it. I only take it out to get inspected for street driving.

 

In that case, i'll settle for the 2013!
