    Heater core lifespan?

    I've never changed a heater core. My oldest car at present is a 99 Dodge Caravan. I drain the rad and replace the lost coolant every 4 years.

    Picture of KIA 1.6 Smartstream cylinder

    IMO, improperly designed and or manufactured pistons. It is developing piston slap. Hyundai makes a lot of bad engines.

    Tri-jets. Any list for No.2 engine failures?

    I worked on DC-10s for a few years and like them. Reversible motor pumps between the 3 hydraulic system made it easy to power up all the hydraulics with one simple electric pump on system number 1. Working on engine number 2 was a little different. The tail cone has a patio that opens up under...

    2012 Santa Fe Kirkland 5W30 12K miles

    I ran many long oci's like this and everything was fine with the reports. Upon removing the valve cover I found heavy varnish and a very small amount of sludge so backed off to slightly shorter intervals. I do like to see someone not afraid to stick their neck out a bit.

    Toyota considers block heater mandatory in certain areas.

    When used appropriately, block heaters save gas, prevent pollution, provided increased comfort and pay for the electricity costs many times over. Perhaps they should be mandatory equipment when sold in a cool climate. I use mine often to save gas but it's a pain plugging in and unplugging.

    Motomaster Filter Thoughts?

    I recently cut apart a Canadian tire OE+ filter and compared it to a Hyundai filter. The Hyundai filter looked superior with about %50 more media and a metal vs plastic bypass valve. I do not consider the OE+ filter worth the money. For $2 more I buy the Hyundai filter.

    Purolator Boss PBL24651 6,075miles C&P

    I would use that filter for twice the interval. Waste of time and money. IMO.

    Kirkland Synthetic vs. Valvoline Advanced Synthetic - 5w30 - Ford EB 2.0

    I just bought some Kirkland 5w30 and it is Dexos 1 gen 3. If the Vavoline has better certifications I would go them. If not, save the money.

    I would guess that nobody ever brake checks a tank.

    QSFS at 5k OCI or HPL PCMO at 10k OCI?

    I would stay away from the HPL as it's expensive and I don't see an API logo on the bottle. As for the QS, it appears you drive mostly highway miles, so a 10,000 mi OCI should be doable.

    GDI Engine Owners - What Oil ?

    10 years with GDI engines. I use cheap synthetic [ store brand or name brand on sale]. Usually 5W30. As long as it meets the latest SAE spec - currently SP. If long trips, in good weather, the OCI will be over 8,000 miles. Short trips cold weather-4,000miles. In my opinion the only thing to...

    2009 KIA Spectra: what oil your use?

    I have an older Elantra with the same engine. Well made in my opinion. I use store brand 5w30 synthetic and Hyundai/Kia oil filters. In your case [8,000 mi/year], I would change oil every 4,000 mi and leave the oil filter on for two OCIs. Replace the timing belt accordingly.

    Silicone vs. Nitrile ADBV

    About a year ago I looked into the cost of making a nitrile valve vs silicone. About $0.03 more for silicone.

    Post Your Latest CAF Change!

    I just replaced the cabin filters in the two Elantras I own, with cheap Chinese white box filters. Normally once a year, I remove the cabin filters, slap them on the ground and vacuum them. They were getting on 6 years old/50,000mi so I thought a change was in order. I can't really tell if there...

    Amsoil OE users chime in!

    Does this oil have the licenses to keep the warranty valid? Economy of scale leads me to believe better bang for the buck can be had with something like Supertech with the Dexos Gen 3 license.

    Stick with what works or change it up…

    In my opinion. Change oil with the cheapest that is SAE SP approved twice a year. Doesn't have to be synthetic. A good oil filter every second oil change. The Hyundai filter is a good filter for the money. $10 each in my neighborhood.
