Recently I've read a lot of stories of rats and other wildlife attacking fairly recent-model vehicles, particularly their electrical wiring. The 'solution' offered by the OEM's on existing cars is to wrap electrical wiring in cayenne-pepper containing electrical tape, that the critters don't...

Have a GM 4T60 transmission/transaxle. Accidentally bought a 4T60-E gasket and filter to service it. Gasket looks directly interchangeable, but anyone know what's different about the filters? How important is changing the filter anyways on these transmissions? Factory filter, transmission has...

I read this online: Quote Heated three and four-wire O2 sensors on mid-1980s through mid-1990s applications should be changed every 60,000 miles. And on 1996 and newer OBDII-equipped vehicles, the recommended replacement interval is 100,000 miles. A good oxygen sensor is essential for good fuel...

What ratios are required generally to achieve a 0W-20 viscosity by blending 0W-16 and 0W-30 oil? I have a stockpile of 0W-30 that I want to run in a 0W-20 application...

https://youtu.be/53IYXsxZDfo?t=868 In a nutshell, the guy, a well regarded, beyond-belief meticulous and salt-of-the-Earth YouTube mechanic's wife recently bought a KIA GDI engine that explicitly spec'ed a fairly high grade synthetic 5W-30 oil. When he called the dealers trying to procure said...

90,000km/10 years since my last oil change, Esso XD-3 0W-30 oil. High temperature Viscosity thickening is a well known feature of long drains. But just searching, I'm not able to find any good material, UOA's, etc., on what happens to the cold temperature viscosity of motor oil subjected to...

http://www.government-fleet.com/article/story/2016/11/when-should-you-change-oil.aspx Quote: Hart began researching oil, oil additives, and filters in an attempt to reduce downtime. In 2010, he began making changes. The fleet purchased an oil analysis machine, switched to extended performance...

Is there any meaningful differences between the various brands of DOT3 brake fluid? I've been buying the dollar-store half-bottles (which are very convenient as you don't have much to toss if you don't use it all up) which are much cheaper, but its not a 'name' brand.

As promised a few times, I finally removed my oil pan to take pictures of what it looks like inside after a 40k mi/6.5 year OCI with Esso XD-3 0W-30 Full Synthetic. Details: GM LH0 Engine (3.1L V6) manufactured 1992 Received diet of either dealer oil or Wal-Mart Pennzoil every 3k from...

Haven't been on these forums for a long time, but coming back, it seems that things are heading in the right direction, ie: OCI's are generally creeping up. Is there anyone else here who runs a truly 'extreme' OCI? Like for instance, I'm closing in on 40k miles (64k kms) since my last oil...

When I go to Rockauto, and try to bring up an ATF filter for my 4T60, I am presented with a bunch of options. FRAM FT1072 ACDELCO Part # TF234 ACDELCO Part # 24227477 etc. They go in price from $9 (Fram), to $18, to a full $30. What's the real difference between these filters? I'll gladly...

My GM 4T60 (aka Hydramatic 440-T4) 4-speed transaxle will need a pan drop and partial fluid change in the next little while. I basically have a few choices that aren't hard to find around here: Dexron-VI -- Mobil, ACDelco (OEM) "Synthetic" Dexron-III "compatible" ATF -- either Mobil-1, or...

Anyone own one of these? What's the consensus for oil? The builders plate recommends pretty much anything from SAE 30, all the way up to 20W-50, from various manufacturers. Its most recent oil change was 20 years ago....so its time for a change :). It takes 14L of oil. I'm assuming that I want...

xW-30 or xW-40? Synthetic or not? Are these engines such that they should have extra ZDDP added to the oil, as either a CI-4 HDEO, or a ZDDP additive like GM EOS?

Its fairly common knowledge that pretty much every car on the road today, with the exception of a small number of diesels, are technologically obsolete, and burn significantly more fuel than would be consumed by a modern, technically advanced engine. 50mpg on petrol, 60+ mpg on diesel not only...

Have one of these engines (I6, 235 ci) in a 1956 Bel-Air, just brought out of storage after 40 years of inactivity. Engine and car has ~50k miles on it, never been rebuilt, original owners, original paint, etc. (even have the factory tyres). Local machine shop says to use GM EOS, with a...

Ok guys. You may remember, in January of 2004, I dumped the Pennzoil that was used in my GM 3.1L V6 (1992) engine by its previous owner (I had just received the car), and installed Esso XD-3 0W-30 full synth. That was 55,000 km ago, and I haven't changed the oil since. I think some people even...

Chemists/Chemical Engineers: which metals are used as catalysts for in the the desulfurization/hydrogenation/hydroprocessing of sour grades of crude oil? I have been told platinum, rhodium, and palladium. Anyone else have some insight? I am thinking of adding to my metals portfolio and feel...

Before I joined BiTOG, I was one of those who subscribed to the train of thought that the owners manual for my car was slightly aggressive in recommending an oil change interval (7500 miles/1 year, 1992 GM 3.1L V6). I believed this, despite, in my professional capacity (at the time), being...

Ok, so most countries outside of Canada/USA use smaller cars (ie: not Impalas/Crown Victorias/Dodges) for their police forces. ie: VW Golf's, Hyundai Accents, etc. Small economical cars, some diesels, etc. Since most police officers in North America are prohibited from high speed pursuits, why...
