This presently shows shipping sometime in the next month, so who knows if it will really happen. That is a good deal for what should be a robust oil. https://www.amazon.com/Pennzoil-550051123-Platinum-Synthetic-Fluid_Ounces/dp/B07TRMN4YR/

One of my vehicles has a hard to reach oil filter which causes me to have to line up the filter with the threads by feel instead of by looking. Most oil filters have the center threaded hole punched into the filter and threaded. Fram Ultras have the base plate showing the sharp edge/end of the...

It has been over ten year since we last purchased a new vehicle. For decades there was always a recommendation to change oil the first time anywhere from a few hundred miles in up to 1,000 miles depending on the manufacturer. Now it seems that most companies say to just leave the factory oil in...

I've been using a lot of PureOne filters over these past several years, but I'm done buying them for a mundane reason: The case seems to be made of the weakest steel of any major brand. Even the highly similar Bosch Premium filter seems to have a stouter can. On at least one of my vehicles...

Previously I have always followed the Honda/Acura service manual procedure of doing four successive drain, fill, drive, repeat cycles for our Honda products. Today I figured there was no good reason not to use the "shade tree mechanic's flush" method of removing a trans fluid cooling hose and...

Recently I bought a no-name Honda fitment filter from Worldpac, the big import car parts distributor. The brand name is "NPN", which I think is a Worldpac house brand. I noticed that the filter looked exactly like a dealer parts counter Honda filter. Then I looked closely at the wording molded...

Up through about the 2002 model year, most Hondas and Hyundais used the same size oil filter (Wix 51344 size). In 2003 Honda changed its standard size to a slightly taller and slightly smaller diameter filter (Wix 51356 size). Honda also back specified the new filter to pretty much everything...

I bought five fresh bottles of SM rated Pennzoil Platinum today and noticed that the label is new: "Superior Active Cleaning Agents" and "Cleans out up to 46% of engine sludge in the first oil change, and continues to clean in the next oil change." I searched and couldn't find a discussion of...

ATF fluid specs seem to all be going proprietary. Ford and GM co-developed their present 6-speed automatic trans-axles in a joint venture. But, I think they each specify their own special fluid, Dexron VI for GM and Mercon LV for Ford. Are these really different fluids, or is this just part of...

I have a two-cylinder electric motor driven Campbell Hausfield compressor I've been using for over fifteen years now. It doesn't get very heavy use, maybe once or twice a week for an hour or two. I hadn't changed the lube oil in a few years and decided to swap it out today. I had nearly a quart...

My friend's Impala has developed intermittent hard shifts from first to second gear and sometimes from second to third. The car has about 65k miles on it. We changed the ATF at 30k miles and again at 60k. Several months ago he took it to a Chevy dealer with the hard shifting complaint and was...

I was surprised to see an advertisement in Popular Science recently where Valvoline claims four times better wear control when compared to Mobil-1 in "independent laboratory tests". They don't say what the exact test sequence is other than "metal loss" and don't provide hard numbers, just...

On modern vehicles it seems that more are hit by the automatic transmission failing as the first really big expense than are by major engine failure. Even so, most automakers compete for bragging rights for the longest ATF change intervals. On my Acura TSX the book says 60k miles for extreme...

I'm doing some routine maintenance on my IR 2131 air wrench, a tool I've been very happy with for years. A few seals are leaking so I got the IR tuneup kit. They call for a special grease, which sadly wasn't included with the tune up kit. The stuff presently in the gun looks and feels just like...

Blackstone's newsletter this month has a long and interesting article about the various classes of motor oil additives: http://www.blackstone-labs.com/newsletter.html

In the past I've never noticed differences in fuel consumption between different motor oils, but recently I changed out the German Castrol 0W-30 in my Acura TSX for some Pennzoil Platinum 5W-30. While still on the same tank of fuel I used the car's built in fuel economy monitor to check fuel...

Does anyone know if the Castrol GTX 10W-30 uses the same quality of basestocks as does their 5W-30? All other things being equal, I would prefer an oil with less VII content. If GTX uses the same quality of basestocks in both grades then the 5W-30 will have more VII than the 10W-30, but if...

As much criticism as Valvoline takes you can't find anything to fault with these recent results. I don't test the oil very often since I am really only looking for things gone wrong rather than obsessing over every oil change. BTW, this oil was free thanks to a Valvoline free-after-rebate deal...

I had a quart of the water cooled (boat) engine type 2 cycle oil I wanted to use up. Having heard of many people burning used motor oil in their diesel engines, I thought that I would try an experiment with my 50 year old MF TO35 diesel tractor with a 4 cylinder Continental diesel engine. The...
