    Fuel trim help

    Check to see if your emissions system charcoal canister is contaminated with liquid gasoline. Another way to test for this is to disconnect the EVAP purge valve and see if the periodic swings towards -100 % stop. Yes, your check engine light will illuminate and a DTC will be set, but it is an...

    Filling up when fuel truck is at gas station?

    Anyone else remember the Amoco final filter that was built into the nozzle assembly at Amoco gas stations in the past? Those were supposed to remove any particulates that found their way into the storage tanks so they would not get into the customer's vehicle.

    Old school 10A battery charger, needs transformer

    Check Goodwill stores, Salvation Army stores, or garage sales. Another thought would be to go to a ham radio "hamfest" and go through their flea market area.

    Drop vs Broadcast Spreaders

    Broadcast spreaders are very forgiving if one cannot push a spreader in a straight line! Much better results than using a drop spreader. I owned a drop spreader for about 3 years and then replaced it with a broadcast spreader.

    Valvoline Top Treat Engine Flush

    It is a solvent. But, according to the Product Information Sheet, it is 100% harmful solvent free (whatever that might be). My question to their marketers is "...not harmful to what?"...

    Looking for I/M Readiness Scanner

    $25 will more than cover the cost of an OBDII setup for an android device that consists of a Bluetooth dongle and the Torque Plus app. Plus, the pair can be set up to log real time information for just about every OBDII system that is monitored to help diagnose problems. Here is the link for the...

    Best Electrical Contact Cleaner

    JWC86 - no methanol from what I see. There is isopropyl alcohol (aka isopropanol, or 2-propanol) which is likely a co-solvent as well as a cleaner.

    How to I.D. an Insurance for a Claim

    Hall, I agree with you, but, the insurance agent should have a set of protocols to follow such as referring their client to the claims adjuster, legal department, etc., for anything other than routine questions. By the way, I do understand where you are coming from as there are many "dumb"...

    How to I.D. an Insurance for a Claim

    A great deal depends on the insurance agent. Some agent's don't give a hoot and will let their client deal directly with the other party's insurance carrier despite it being their job to represent you and your insurance carrier. I learned a long time ago from my uncle who was an insurance...

    Battery maintainer and sensitive electronics

    Another thing to remember is that a good battery is one heck of a filter for the voltage that comes out of the maintainer, and will also absorb many of the voltage spikes.

    Cut Open : AC Delco : NEW vs. OLD

    I looked them up. The PF2 was used on a lot of Ford V8 engines like the old 390s that were common in the late 60's Galaxy 500s and LTDs. The PFL400A was used on a lot of 4 cylinder and V6 engines. Both filters do have the same threading and pitch, but they have different outside diameters and...

    Rislone High Mileage Oil Treatment - Contents ?

    In looking at the Safety Data Sheet (SDS) it appears that Rislone Engine Treatment is little more than ZDDP (also known as Zinc diakyldithiophophates - which is a "mixture" of zinc containing compounds that are soluble in nonpolar solvents such as oils) and petroleum based ingredients. In...

    Old oil can

    You could be right. I was just relying on old memories. I just remember that whenever we saw single cans (usually after running a forklift through the bottom layer of a pallet of oil cases or just flat out dropping a case while moving pallets around) they were typically metal cans. Those of us...

    Old oil can

    Based on my having worked for a Pennzoil distributor (we also sold most every other brand as well) in the 1974 - 1976 time period, when the switch from metal to paper cans began, I would say we started seeing the paper Mobil cans late in 1974 or early in 1975. I also remember when Pennzoil...

    Push Mower - which carburetor?

    If you want to add something to the fuel in order to clean the fuel system, use Berryman B-12. As far as any "tune up in a can" goes, there really is no such thing. More than likely, cleaning the fuel system of varnish, dirt and other crud is what restores power, etc.
