Motor Oil, what's the best?

I dont know about that whole 25k deal, i would probably do a filter change at least every 10 maybe less
Ive been using RP but am tired of paying so much and have been running whatever was on sale (reasonably, not the SEMI-full synthetics) usually mobil 1 or penzoil
I heard mixing dino and platinum isnt a good idea...i dont know, just read it somewhere

For multi-grade viscosity oils, the cold temperature viscosity is labeled with a "W", which stands for "winter" (I'm not ashamed to say I always thought it stood for "weight") Thus, in SAE 10W-30 oil, the "10" is the cold-temperature viscosity rating, the "30" is the high-temperature viscosity rating. This provides an oil that flows well at low temperatures, but still protects at high temperatures.
This brings up the question, how low do we go? Our Dodges recommend 5W-30, I guess based on what I've just learned, I'll use 5W-30. I always used 10W-30 in new and 10W-40 in old cars.
Synthetic for all ages...Myth: You shouldn't use synthetic oil in older vehicles.
Synthetic oils will enhance engine protection in older vehicles just as they do for new engines.
There was a time, years ago, when switching between synthetic oils and mineral oils was not recommended if you had used one product or the other for a long period of time. People experienced problems with seals leaking and high oil consumption but changes in additive chemistry and seal material have taken care of those issues. And that's an important caveat. New seal technology is great, but if you're still driving around in a car from the 80's with its original seals, then this argument becomes a bit of a moot point - your seals are still going to be subject to the old leakage problems no matter what newfangled additives the oil companies are putting in their products.

Is There Any Harm to Mixing Different Mobil 1 Viscosities?

Answer:
Today’s modern vehicles require less viscous oil in many cases than in the old days. Having said that there is no harm in mixing different viscosities of Mobil 1. They are all compatible with each other.

That's funny.
I was just in the ole shop they told me there was a firmware update to the computer, cause it was reading the wrong oil pressure...I was running 10W-40 in there at the time.
It was explained to me, it was a Dodge issue not and engine issue.
This was Oct 10th or so.

My 1968 Ford Mustang GT (302 c.i.) has over 240,000 miles. My parents have two Jeep Cherokees (242 c.i.), each, with over 225,000 miles. I began using Valvoline DuraBlend (semi-synthetic) in the Ford at around 190,000 miles. It was nothing but conventional oil before that. My dad uses conventional oil in the Jeeps.
I use nothing but Mobil 1, in my 1998 & 2003 Jeeps and in my 2005 Dodge. My goal is to make it to at least 300,000 miles, still running strong, with these vehicles.
