    Honda Remanufactured Transmissions

    I’ve been offered a goodwill replacement on a Honda transmission with Honda kindly picking up the majority of the cost. Even so, this is far from a freebie to me. My existing transmission is original and under 60k miles but time has expired on the factory powertrain warranty. The problem the...

    Fluid Leak from Torque Converter to Transmission

    There’s been a discussion on a Honda forum about an issue with its CVTs as described in TSB 18-072. The issue is excessive clearance between the torque converter stator and transmission input shaft that allows fluid to slowly seep from the torque converter to the transmission. When a cold start...

    2007 Ford F-150 FX4 4.6L

    An out of town friend has asked to look at captioned truck. Photos look nice, only 31k miles and fleet maintained. I know little to nothing about this vintage - other than the usual used car stuff is there anything in particular that deserves attention? Thanks.

    TPMS False Alarms

    My Honda CRV has an “indirect” TPMS that has produced a few false alarms lately. When first back in the garage tire pressures are within 1 PSI or so among tires (one side higher than the other) and slightly above the door placard recommendation. After garaging overnight, pressures are within .5...

    Battery Change

    So my dealer tells me my 3 year old Interstate battery is testing low and should be replaced. And remarkably, Costco says to bring it in for a replacement no questions asked. It will take an hour or two to retrieve the replacement. What’s the best way to preserve the car’s electronic memory in...

    Oil Volume vs Temperature

    As noted here (I think) and in the “Engineering Toolbox”, oil volume expands with increasing temperature. And if I’m interpreting the “Toolbox” graphs correctly the increase is of some significance: from room temperature to 100C on the order of 5-6%. So when we buy a 5-quart jug of oil, at what...

    Bad Catalyst? Corrosion Strategies?

    The car in question is a 2008 Mazda MX 5 (nee Miata). 26,000 miles, summer use only, stored winters in a garage in northern Wisconsin. This is a vacation home that isn’t visited from November to May. Yesterday I noticed a rattling sound from beneath the car, sensitive not to road speed or load...

    A New One on Me

    I've been changing oil on my cars for 50 years or so, so this ain't my first rodeo. But I had a new oil filter oil experience (sad, isn't it, when new experiences are oil filter-related). Changed the oil on my 2015 Honda CRV about 2,000 miles ago and used a Wix filter for the first time. I used...

    Front/Rear brake balance

    My 2017 Acura TLX seems to have brake balance very heavily biased to the front. While some of this is normal in fwd vehicle in my case it seems extreme: rust on rear rotors from rain can persist for weeks even with regular brake use. I'll take it in to the dealer but expect the usual "it's...

    Winter storage - fog cylinders?

    I have stored an MX-5 over the winter for a number of years. Every year I've fogged the cylinders as the last part of the storage prep process. Stored for about 6 months in an unheated garage in a cold climate. It's an in-line 4 so not a huge effort, but wonder what others do. Anyone here do...

    Updated Shell PDS Information @ Epc.shell.com

    Just as an FYI, Shell’s website has been updated to reflect Pennzoil Platinum’s designation as an SN Plus engine oil. Specs are a little skimpy (no HTHS or Noack), but are at least available. The marketing verbiage that goes along with th TDS notes that it has been “Redesigned for modern...

    New Ford 1.5 Liter

    According to Motor Trend, Ford will be replacing its 4 cylinder 1.5 liter TGDI engine with a 1.5 liter 3 cylinder TGDI. It will also have cylinder deactivation, enabling it to run on 2 cylinders under some conditions. First use is expected in the 2019 Focus and then likely to the Escape and...

    Understanding HTHS

    High Temperature High Shear viscosity is a (the most?) important specification for each oil viscosity. But I’m not sure how it relates to everyday engine protection. Using 20 weight oil as an example, my understanding is: * 100C viscosity should be in the range of 6.9-9.2 cSt * HTHS must be...

    Pennzoil & SN Plus

    Noticed on the Pennzoil website that Pennzoil now says its dexos1Gen2 oils are “SN Plus Ready”, and will be labeled as such at the earliest allowed date: May 2018. It makes sense that oil makers would not reformulate separate oils to meet d1G2 and SN PLus, but Pennzoil,is the first I’ve seen to...

    Battery change memory savers

    I have a new "memory saver" that attaches a 12V power source (e.g. Spare battery) to the car's OBDII port during a battery change to save radio presets, PCM "learning" and the like. This seemed like a "no-brainer" and a smart thing to do but I see conflicting advice on, you guessed it, the...

    DI/TGDI Response to Spark Knock

    It seems understood that OEMs program their DI/TGDI engines to richen the fuel/air mixture in conditions where LSPI could occur. This question isn't about that. All modern engines have knock sensors that detect "pinging" or spark knock other than LSPI. In the pre-DI/TGDI days, the response to...

    Fogging cylinders for winter storage

    When storing a car for the winter does anyone fog the cylinders? I store my MX5 in an unheated garage in a cold part of the country. It will be untouched from about now until Mid-May. I've stored it for a number of years without trouble but have always fogged the cylinders as part of the...

    Honda 1.5T

    Though I don't own one I nevertheless became involved in a discussion about fuel dilution in Honda's 1.5T engine on a different forum. As part of this I looked for every UOA I could find on this engine and found a dozen on Civic forums. Of this dozen: 1) 5 had fuel dilution tested by gas...
