    Mazda SkyActiv FZ 71,210mi

    I'm posting this on behalf of Mazdas247 forum member. I thought this might be of the interest, as Mazda ATF UOAs are not widely represented here. The vehicle is CX-5 with 71,20mi at the time the sample was taken. This particular transaxle does not have an easy way to perform a complete fluid...

    DIY catch can material?

    I didn't get a response in older related thread, so I will try again. I have two different catch cans connected sequentially in my Tahoe. That works well, but now I'd like a catch can in our Mazda, and I will transfer this setup there. I am thinking about building a large catch can out of 3...

    Where is the oil temperature sensor on Tahoe?

    I searched Identifix and couldn't find out where does the engine oil temperature reading is coming from. I can get it on Scangauge and my Maxidas scanner, but I can't figure out where the sensor is. Is it bundled with oil level sensor? 5.3L 2014

    Round-the-clock battery maintenance- good or bad?

    I have <a href="https://no.co/genm1" target="_blank"> NOCO GENM1 4-Amp on-board charger/maintainer</a> installed under the hood of my Tahoe. It is a part of the offshore 120V power devices grid on the car that are connected to power through wifi timers, so I can control the timing and what...

    Gm V8 shaking in idle

    I have '14 Tahoe with 5.3L. Whenever I come to stop after driving, the engine doesn't idle smooth. Well, it does, for about 20 seconds. Silky smooth. After that, I can feel a faint shake through the floor. Before you say you don't feel it in your truck, put your left knee against the door trim...

    2014 Chevrolet Tahoe 5w30 5.3L QSUD???+MoS2 10k km

    Two samples from my Tahoe. In my infinite wisdom I forgot to write down what oil did I use for the latest OCI. I only use PP, Castrol Ti or Edge, and QSUD. This is not Castrol, as there's no Ti. Most likely QSUD, but the additives don't match the previous sample. Oh well... Maybe someone has...

    QSUD/Castrol 0w20 2015 Mazda CX-5 2.5L

    Here's a couple of results of UOA done by two different labs that are local to me. This is convenient, no mailing involved. Although both provide sufficient information (I guess), WearCheck goes into more details. The car is 2015 Mazda CX-5 AWD 2.5L gas. The oil is changed every 4 months, as...

    Smoother ride option for Tahoe?

    I have 2014 Tahoe LS with ZW7 "Premium smooth ride" option. The rear shocks are self-leveling Nivomat type. I generally like the ride, however it becomes quite harsh on the "laundry board" type of surface. I'd like it more plush. I'very been thinking about replacing stock Nivomats with something...

    Reason(s) for V8 not being smooth at idle

    My 2014 Tahoe (previous gen 5.3L) is silky smooth at idle. That is, when the car comes to the stop, and this lasts for about 5 seconds. Then the RPM begin to fluctuate quite a bit, between 490 and 530, and it is quite noticeable. It doesn't pass water bottle test at all, and the vibration could...

    GM GEOS

    <a href="http://www.imakenews.com/lng/e_article001231711.cfm?x=bdvwmT5,b8M0dgwD" target="_blank">New GM Spec</a> I am not sure if this is an old news, but looks like there's a new global oil spec coming from GM. What happens if they franchise it as Dexron III? I smell new prices...

    Pulling in or backing up?

    Yesterday I've heard on the radio that there are benefits in backing up into your driveway when you're done for the day. The rationale was that in reverse the cold ATF is under much higher pressure then in forward, creating a "big bang", which is not good for the tranny. Is there any merit to...

    Pressurized crankcase

    While fiddling with my catch can setup I discovered that: 1. I have positive pressure in the crank case at any RPM. When I remove a dipstick, the gases (oil mist) blow from there. The same is true for the oil filler cap. But: 2. There is a good flow through PCV valve, smaller at idle...

    Free Amsoil SDF-10 filters

    I think I've got intended benefits from my Amsoil Dealer status three years ago. I stocked up on great oil and was able to pick it up myself from the warehouse, I befriended my neighbors selling them good stuff, etc. I also bought about ten SDF-10 filters to use in my car. In fact, I have not...

    Havoline SL GF-3 5w30, 5200km, Suzuki Aerio 2.3L. Low Moly?

    I've got 10 bottles of Havoline oil for free (after coupon) few months ago. I learned from people's experience that it is rich in Moly and a good package overall. I run two consecutive 5k km OCIs on it and pulled the sample at the end. Wear numbers are good, but the absence of Moly really...

    '03 Corolla transaxle

    My brother-in-law has imported Automatic '03 Corolla (about 60k miles) from the US to Ukraine. This engine/transaxle combination is pretty uncommon over there, and he keeps asking questions that I try to find answers for. My nearest auto shop did not have repair manual for this model, so I have...

    Investors, anyone follows MF's Hidden Gems?

    I hope that's the right board for this question. I noticed quite a few investors on this forum, and I would appreciate anyone's comments. How many of you are subscribed to Motley Fool's Hidden Gems? Any other MF's service? Does it influence your investment decisions in a way? Is that a good...

    Starting problems

    <blockquote>quote:<hr /> It only has 15k miles so would it actually have something to do with the spark plugs?<hr /></blockquote>No, not in this case. Depending on what kind of dealer you will be talking to, the result could be a complete waste of time (and money), or a pleasant success story...

    M1 5w30 SL+LC 9766km '04 Suzuki Aerio 2.3L

    This is my first and last UOA with M1 5w30 SuperSyn (not EP). All the analyses had been done by WearCheck Canada in Mississauga. The engine is 4-cyl DOHC, chain- driven cams. The oil had been in use for four month, from Nov 10, 2005 to March 11, 2006. There were no temperature extremes this...

    Automatic oil change system

    I found this article in SAE's November "Automotive Engineering" issue to be interesting. I currently do not have web space to host images that come with it. <blockquote>quote:<hr /> Specialized Enterprises (SEI) has developed an automated fluid exchange system that dramatically reduces the...

    LC & FP in Ontario, any takers?

    For those Canadians (well, I guess mostly Ontarians or even GTA dwellers) who would like to buy FP and LC on the spot locally, I plan to get a trial commercial shipment into Canada in not-so-distant future. Currently I’m trying to figure out what is involved customs-wise and finalizing pricing...
