I have a 2006 Mazda 3s. It has 42k with the 2.3 and a manual transmission. I use only Mobil 1 synthetic oil. You are quoting the manual for the service intervals. My manual only states using 5w-20. Is there a reason you are using 5w-30? Will the oil have any trouble with the tight tolerances? Thanks, Halser

Replying to: halser (Mar 06, 2009 11:58 am) In my case I'm running 0W-30 in my 2009 Mazda3 i Touring (with the 2.0 liter engine) 5-Speed, and like your 2.3, the physical engine block, crank, pistons, heads and valve assemblies are identical to the ones sold in European Mazdas, and those engines call for 5W-30. For the U.S. market, the reason 5W-20 is recommended has nothing what-so-ever to do with tight tolerances and everything to do with getting the best fuel economy numbers. Best regards, Shipo

2004 with 53K miles Power steering unit decided to function intermittently last year. Now it is completely dead. The dealer wants an arm and a leg and my first born child to replace it. Has anyone else been through the diagnosis and replacement of this unit? Any tips? Do you have to reset the computer after replacement? THANKS!

Replying to: drpr (Mar 10, 2009 3:31 pm) Have you checked the power steering fluid? Have you ever had it replaced? Do you see any leaks under the engine? Did the dealer quote a new unit or a replacement unit? I had to have mine replaced last year after I ran over a speed bump the wrong way and created a crack in the unit which slowly dripped out all the fluid. I had a replacement unit installed upon the dealer's recommendation at roughly 1/3 the cost of a new unit. Good luck!

Replying to: autonomous (Mar 11, 2009 3:19 pm) No leaks, Good levels, Not replaced since I bought the vehicle a year and a half ago. The dealer didn't think replacement fluid would have any effect. They quoted me on a new unit and indicated that was the only option. I will have to recheck that. Was yours a rebuilt? Anyone out there replaced the unit themselves? Thanks!

Replying to: drpr (Mar 11, 2009 4:00 pm) Yes. If memory serves, the factory unit was approximately C$2000 and the rebuilt was C$800 (Canadian $ is currently worth about U$.80). In addtion to the unit, you will need to have new power steering fluid and a wheel alignment.

Well, I'll be driving back from Vail Co to Maine and Colorado winters are easier on you than back east. In Maine at camp it gets 20 to 30 below so that the inside hinges on you're camp door frost up.In CO the the Rockies block out alot of bad weather and you have ten straight days of sun and the trees give off heat. The only thing I know is the Mazda dealer told me to always use semi syn oil 5w 20. The air is thin here and I feel that my Mazda 3 I touring is lagging due to thin air, and the Dunlop tires I put on for the snow.Now, I use 5W 30 in the snow blower. Maybe ,I should be driving a car such as Roadburner has. A natural aspirated car struggles here. The base lodge is 8000 feet above sea level. Alot of people have GTI's, WRX's and Subie Turbo's and a million 4x4 pick up trucks .I haven't seen A Mazda Speed here.
