Here's some data I collected for some SG and SH* oils. Ed Brand VI Flash Pour % ash % zinc 20W-50 AMSOIL* 151 507 -45 AMSOIL Series 2000* 155 474 -47 Castrol GTX* 122 440 -15 .85 .12 Castrol Syntec Blend* 135 440 -17 .105 Chevron Supreme* 140 428 -17 <1...

I would be very reluctant to ascribe anything nefarious to Exxon Mobil, or any other top tier producer. There are multiple "innocent" ways an oil can get out of, or test out of spec. Most would result in a short term problem, such as the stacking of normal batch to batch variation with the...

Of course they didn't. They endorsed the product and they chose to protect their corporate image. OEMs not backing a claim does not change the data. If you believe that the data provided by Shell is in error, show me independent testing of that lot of oil that proves it was in compliance. Ed

It looks like ARCOgraphite has posted the Valvoline data concerning the Mobil 1 5W-30 SM oil. Here's a link to Shell's published data concerning Delvac 1300 Super 15W-40: Shell Volvo T-13 Data Ed

Mobil 1 5W-30 SM was demonstrated not meeting Sequence IVA requirements. Mobil Delvac 1300 was demonstrated not passing the Volvo T-13 oxidation test. Rotella T6 is shown here not meeting the foaming requirements. Yup, just buy a major brand and you'll be assured of getting an oil that is...

This is from what I assume is the listing for those drives on Amazon: SeeDete 64GB USB Flash Drives Those drives are writing at USB 1.1 speeds. Welcome to 1998! Ed

DoD Nominal yet? Ed

House on a slab, ac/heatpump roof mounted with ducting in the attic. Cheapest possible construction. The unit is likely one of these or a similar model: https://www.goodmanmfg.com/products/packaged-units/heat-pumps/gphm3 Ed

Copper will gladly catalyze oxidation of the oil if left to its own devices. Ed

Absolutely. Unfortunately, unless AMSOIL or some other boutique formulator chooses to run the tests and publish them, we have no way of knowing which oils do or don't. The major oil companies certainly aren't going to provide that information to you. It looks like ACEA C6 would be a good...

That would appear to be the case. ACEA C5 and C6 address oils with an HTHS viscosity of 2.6-2.9, which would include 0W-20. They don't appear to address oils with an HTHS below 2.6(0W-16) yet. The ACEA sequences include a Toyota test for turbo deposits in diesel engines. The only HTHS range that...

0W-20 is exempt from the TEOST 33C test. The add is disingenuous by including the GF6 limits applied to the other grades of oil. It successfully tricks people into thinking other oils don't met the standard but AMSOIL does. 0w-16 is exempt from the sequence VIII test for bearing corrosion. The...

That's a tandem breaker. It's two single pole breakers in a single width housing. They're a "kludge" used when there are not enough spaces in the load center. They are fine to use, but are not as durable/reliable as a full sized breaker. Using it for two 120V legs to create a 240V circuit would...

It says the equivalent must have the API Donut trademark. That means certified. Show us the API Donut on the bottle of Euro VX. Ed

In Jules Verne's "From the Earth to the Moon", written in 1865, the travelers encountered a problem and calculated a path to slingshot around the moon and return successfully to Earth. Apollo 13 used the same maneuver. A quick look at wikipedia shows that the knowledge to calculate this was...
