Clearly the Amsoil produced more wear metals. It's right there in the samples. But several people in this thread have asserted that those findings are bogus and/or not to be trusted. So if we had 50 samples that showed the exact same wear metals with Amsoil, and 50 that showed lower wear...

ALL auto parts stores are using HUGE mark-ups. I discovered this about 15 years ago when I needed a radiator for a Jeep Grand Cherokee which was a second vehicle. The auto parts stores of course wanted $200 to $300 for a radiator depending upon "grade". Being a second vehicle, I ordered a...

So you guys are asserting that maybe 10 or 20 oil cycles on each oil would be needed to get a clear picture of how the engine reacts to each? I'm not a tribologist, but I did stay at a Holiday Inn Express last night, (and I have a science background with statistics and data analysis in my...

Discount Tire and other shops always over inflate my tires on the F-250. I assumed it was for liability reasons. I.e., more pressure is safer than less pressure. See the Ford/Firestone cockfight from the 1990s for the root cause.

While not "budget", I'm on T-Mobile at $80/month but I get priority 5G data, 250 gigs of 5G hotspot, and best of all they turned on "T-Satellite" service last week which now means I have no dead spots anywhere in the nation as long as I can see the sky, and to me that is WELL worth the cost. A...

Wow, the Valvoline Premium Blue has the second lowest phosphorus in the bunch? I thought Phosphorus at or above 1,000 was a critical component of a lot of the modern specs the OEs use?

Temperature not going below 20F this coming winter? Then rock the 15W. I can't use it here where I live.

That, combined with the fact that temperatures here go at or below 0°F each winter is why I will not run a 15W40 in my trucks. According to the chart in post #1, which I think came right out of the owners manual, 10W30 is on the ragged edge of good flow and protection at 0°F. And a LOT of the...

"You are not required to use an oil from Ford's approved oil list, and Ford cannot deny warranty for using an oil that isn't on their approved oil list. The oil only needs to carry the correct Ford specification (WSS-M2C171-F1) and meet the correct viscosity requirements. AMSOIL will never be on...

OK thanks. As far as “what are we gaining by switching?” goes, not much. Just convenience, and the *perception* of getting a better oil. I’ve read on this forum a lot of horror stories with Rotella. So I just assumed that since everyone praises Amsoil like it’s liquid gold, and I can order a...

Well Rotella is trash, so I guess I'd have to stick with the Valvoline PB that I've been running, or the Motorcraft 10W30 that's factory fill and also easily available.

Here's a link. Looks like 5W40 or 10W30 are the options. I usually tend to like 5W40 because winter here does get to 0°F or occasionally below, but summer gets above 90°F regularly. I do NOT intend to go 15k between oil changes...

Their site shows these two options for my F-250 6.7L. There is a fairly significant price difference between the two. Both claim to be 100% synthetic. What is the main thing I'm giving up if I go with the Heavy Duty version?

Would sure be sweet if some 5W40 oils on the shelf would be a good fit for these 6.4 Hemi engines. 5W40 options are so much easier to find.

That's what I use also: Valvoline Premium Blue 5W40. It's only $25/gallon at my NAPA. Have any members here gotten oil analysis on this oil to prove it's better than Rotella?

I've been running Valvoline Premium Blue 5W40 in my 2019. I get it at NAPA for around $25/gallon. My difficulty has been the filter. Somebody said the Motorcraft filters are made by Purolator, and Purolator was bought out by a huge conglomerate who lowered quality. So I have tried the...

You jest, but that's the first vehicle I ever got pulled over for speeding in.

How are they going to get meaningful product without a leader who "gets it"? They put the perfect guy in charge. He knows the U.S. consumer and he knows how to develop product that will sell. If they leave him alone, which Tavares didn't do, Ram will rebound next year. Just watch.

None. I wouldn't buy 0W20 unless it was literally the only viscosity available.

As long as he leaves Tim Kuniskis alone and lets him do his thing Ram will regain market share in 2026 and after that the Dodge brand will pick up steam.
