    Fuel economy season

    This past week, the '97 Accord on PZ yellow 10W-40 did 32.6 mpg. The '99 Accord on GC did 32.7 mpg. Both were run about 380 miles before filling. Now, is it just me, or does everyone else see noticeably better fuel economy in the mild temperatures of fall and spring? Winter fuel economy is...

    GC and fuel dilution

    I tried searching this topic, and found nothing. I would appreciate any help. I have been using GC in the '99 Accord my wife drives. She may have a very short commute over the coming winter, and I am therefore interested in an oil that does well with excess fuel. How well does GC deal with fuel...

    Alternative vehicles?

    I paid as much as $3.49/gal for regular this year. This was only a spike, of course, but it came when the low fuel light was on, meaning I had about two gallons (60 miles, more or less) left in the tank of my Accord. I have considered a small displacement motorcycle or scooter for somewhat...

    What gives used oil a foul smell?

    Drain oil is usually noticeably darker than fresh oil, and sometimes has a strong smell. Now, oil from a diesel has a jet black look (at least out of one of the old 240Ds I had) and has a distinctive smell. Oil drained from a gas car may smell rather foul. I drained PP 5W-30 from my '97 Accord...

    Penz yellow bottle 10W-40: Feel the quiet

    I put PZ yellow bottle 10W-40 in my '97 Accord a couple of weeks ago, and was astounded by how much less mechanical noise I heard compared to the PP 5W-30 that was in it. I have a small stash of the 10W-40 left over from a now destroyed Mercedes, and I need to use it for something. Honda allows...

    Crown Vic and the Ford OHC V-8

    Not sure whether this belongs here or not, so please bear with me. I bought a couple of Crown Vics with a bit under 100K for our perimeter patrol. We have replaced both of the cars' engines with low mile salvage units, at around 150K. Oil consumption had gotten ridiculous, to the point that our...

    Syntec SJ PAO or hydrocracked?

    Some of you have noted that certain retailers have kept certain oils on their shelves for an unusually long period of time, like a decade. The local K-Marts have a bunch of SJ Syntec, which they appear to finally be considering perhaps putting on clearance. My question is, would an SJ Syntec be...

    Advantage: Mercedes

    I have advocated old school Benzes as good cars for young drivers. A couple of hours ago, our twenty year old got involved in an accident with my lovely old W201. The 190 has rolled its last mile, but the airbag on this nineteen year old machine still worked, and, more imporatantly, my son is...

    Slick 50 Full Synthetic Oil

    Does anyone remember this stuff? I bought a decent stash from Big Lots back in the late 'eighties, I think it was. The oil was a 10W-30, and I used it in one of our '86 Civic Wagons for a few OCIs. I am thinking that it must have been a Grp IV, since the hydrocracked Grp IIIs did not yet exist...

    Short first run of GC?

    Friday, the '99 Accord will get its first fill of GC. This car has had only two 3k runs of dino in its 90K, with the rest all being what I now know were Group III syns. I am planning OCIs in the 5-6K range, and I wonder whether I should make the first run of GC a bit shorter?

    Best car you have owned long -term

    Okay, I don't want to see this thread devolve into a GM vs Ford vs Toyota vs Honda slugfest, so here are the rules: You have owned the car at least ten years OR You have driven the car at least 150K Based upon the above criteria, the best car we have ever owned was a 1986 Honda Civic...

    Will driving in the rain decarbonize the heads?

    We made a recent trip where it rained contiuously for 230 miles in both directions. The rain ranged from moderate to deluge. My question is this: If introducing some water into the intake air is known to remove carbon from the heads and the piston crowns, would a long trip through varying rain...

    What design elements make an engine last?

    We all know that certain engines have great life expectency, while others are doomed to death at relatively low mileages. This is without regard to PM or use. Some, as a group, just don't hold up. The I-6 Jeep seems to be a standout, along with the old diesel Mercedes 4 and 5 cylinders, as are...

    Bean Oil

    Does anyone know whether there are any commercial bean oils out there? Back in the day, Castrol R was based on castor bean oil. I also recall reading years ago about a motor oil based on jojoba bean oil. Was such an oil ever offered commercially? I have read that castor bean oil had oxidation...

    Need car for work, only have 3K, what to buy?

    Let's say it's Thursday. You are on your way to work, and your ride suffers an unmistable terminal event. You call in Thurs and Fri. By Mon, you must get to work. You need a ride, and don't have much to spend. What to buy? To answer myself, my heart says Honda, but my head says something with...

    Worst Engines

    There are a couple of threads now running regarding the best engines. I think we have this backwards, since most engines are pretty good. Therefore, I am starting a worst engines ever thread. My nominee is the Vega 2.3l. I owned one way back when, and it used ungodly amounts of oil (like 1 qt...

    Minivan tires

    I am new here, having just registered a week ago. I have learned a great deal from BITOG. Some of my cherished myths have been debunked. For example, I will probably not buy another Fram oil filter, which I have long used based upon my perception of their quality. Anyway, can anyone offer their...
