I was down pretty hard on Ford's Ecoboost effort, labelling them as largely failed. However, that whole approach may have a future. Its a partial success, half-failure, trying to gain fuel economy while delivering power using a smaller blown 4. Anyway, to get a look at what that ubiquitous 2.0L...

On the recent GM 2.0L Turbo 4 and 2.5L 4 engines, the spun bearings that occasionally popped up, was it that the bearing clearance was too high, too low, out-of-round, flat spot, surface roughness, metallurgy or heat-treating? Does anybody know? Big-end bearings. Oil film "disrupted", meaning...

Does anybody know how often they changed the oil filters on the Mobil1 Land Rover oil experiment, driving around the world? Pictures of the valve covers off in the link below. Maybe some remember the Mobil1 synthetic oil test in around-the-world driving in a Land Rover where they didn't change...

What changed in 2011? this qoute: "As little as a couple of seasons ago, engine wear was such that an engine nearing the end of its multi-race cycle would be significantly less powerful than one at the start of its life. That is no longer the case, in large part thanks to advancements in...

What do they make all-synthetic oil filter media out of usually? No cellulose paper for sure. Glass fibers and polymer fiber blends? All polymer plastic fibers? Supermodel hair?

While the Purolator Classic oil filter tear issue continues, I have been emailing a Purolator rep, and he claims they do not routinely simply gather used oil filters to cut open. Since BITOG members cut open filters, and cutting them open reveals failures, I don't see why a big company doesn't...

Some interesting things at pennzoil.com Pennzoil Platinum Ultra is now dexos1 (again after an absence) and the Ultra's NOACK shot upward from 7 to 11, not good. Pennzoil Platinum lists a new Euro 5w-30 and 0w-40, LL-01, MB 229, Porsche A40 category, which I guess is what the BMW dealerships will...

If we had a split oil sump (2 oil pumps), one sump fed the valvetrain and timing chain areas, and the other sump fed the piston ring and crank bearing areas (near combustion), what oil would be best for the valvetrain one, and what oil for the crankshaft bearing one? Would the valvetrain one...

I use cartridge filters in both my cars, where the media is not surrounded by a metal can, making the media visible and accessible. ... Is it possible to buy Synteq media, or maybe whatever Amsoil uses in their bypass filters, just the media? ... I want to take a strip and lay it along the...

Anybody know of an oil condition sensor product that replaces the oil drain plug? My 07 BMW 530 has one already, yet my 11 Camaro does not. Or maybe just a good one to get for home use to test a sample of oil. References: http://www.lubrigard.com/products/literature/LG-OCS-1.pdf...

What would be the best choice for lowest wear on engine timing chains? The GM High Feature V6 (LLT 3.6L) made for the past 10 years has had some failures (stretching, elongation) and GM says its some combination of poor oil lubrication and materials needing hardening (carbonitriding was...
