    Ok, so I know there are multiple threads on what oil to use, I would like to post here my discoveries. I have tried multiple oils in my 3. Mobil 1, Valvoline, Castrol Edge (which I have used the most). I often check my oil and do the old Biden sniff test. All of the synthetics I have used have...

    I was told that I have a bad oil leak(more like a pour) coming from my 2017 mazda 3 sports front main seal. In order to get to that you have to remove the crank pulley and I was told on some mazdas you can not just remove the pulley because it will mess with the timing. Delership warranty won't...

    My 2016 Mazda 3 is at 71k miles, so I figured I'd replace the spark plugs. When I pulled them out, one looked like this: There was oil on the bottom threads but the top was clean. At first I thought valve cover gasket, but now I'm thinking the piston rings might be shot. The strange thing is...

    allot of people saying overfilling your oil can damage your engine, the dealer I got it from added 5L instead of 4.2L to 4.3 depending on what the manual says, and told me it should be fine since the skyactive engines where made to handle it, I want the honest truth from you guys.. should I go...

    Hey guys, I recently discovered oil droplets forming under the water pump but can't directly see the source of the leak. Anyone know where this could be coming from? See the attached images and this video I took for reference:

    I purchased a new 2018 Mazda 3 with around 650 miles on it. I'm assuming that it was used by the dealer for many short rides. Because of that I made sure that they included a free oil change when purchasing the car. I got the free oil change coupon (which I need to schedule), but was...

    I am having trouble installing the oil pump pickup Tube on the oil pump of my 2004 Mazda 3 S. I have the original gasket and a new gasket. They are not true O-rings. The cross section is taller than the width at the CL. The pickup tube has a shallow recess that I assume is for the gasket to fit...

    I need help with installing the oil pickup tube to the oil pump of my 2004 Mazda 3 2.3L engine. The pickup tube has a recess that looks like it is for a regular o-ring. The gasket (?) that was originally installed does not look like a regular o-ring. The rings profile is not circular. It is...

    I have a 2007 non turbo 2.3L engine and I was curious if a Oil Pan from a 2.0L will fit on my car? It seems all the bolt holes match up. Would like to know before I drop the broken pan and try to replace TIA

    Hi folks, During my oil change this weekend I noticed something that I do not recall from the last change. After warming it up for 3 minutes (from cold), with the engine off, I opened up the oil fill cap before diving under to pull the drain plug and noticed a decent amount of visible vapor...

    The dealer recommends that I change the oil at every 5,000 miles, while the service manual say 8,000 miles. Which one is right? Paul

    Greetings all...yep...it's an oil thread. Please accept my apologies in advance. So when I bought my car the dealer set the maintenance minder to 'scheduled' every 5,000 miles with oil change and tire rotation turned off. Once I got it back from my first free oil change, I turned the scheduled...

    Hi, I've had my 2006 M3 S Hatchback for about 6 months. It's got 144,445 miles on it. I had the oil and filter changed right after I bought it and have put about 1,500 miles on it. Yesterday, the oil warning light flickered a few times so I checked the oil and it wasn't even showing on the oil...

    Hey everybody, just got a Mazda 3 for the first time after almost two decades in Hondas. Loving it so far but I seem to be at a loss for something incredibly simple - how do I see the current oil life %? I can't find it within in the left or right speedometer dash displays when I toggle...

    Hey everyone this afternoon I felt like checking out my intake valves for carbon and soot buildup as I hand scrubbed them 10,000 miles ago at 50k (you can find these images on page 2). I was pretty surprised to see a moderate amount of carbon build up on the right most valves and quite a bit of...
