mobile 1, vs amsoil, vs other kind vs napa

One more note...
The paraffin might not be a bad thing as far as providing good lubrication, but like any wax would do, it cakes up over time and causes build up. Most experienced engine builders know this about Quaker State/Pennzoil. Ask around. And no Tim, you are not what I would call "experienced" (no offense)... by “experienced”, I'm talking about someone who's been in the business 30+ years or so (not 20+ years-old). Them old fogies occasionally get one right... you might try listening to one sometime.... /forums/images/graemlins/ignore.gif
 
Oh, and another...
Those "Oil Bible" sights seem to only discount additives and "wonder oils" like ProLong, Z-Max and Slick-50. They don't comment too much about the content of common motor oils.
 
The site I liked to has comprehensive breakdowns of EVERYTHING in nearly every oil on the market.

Read it.

I've heard old folks talk trash about pennzoil. It's nonsense and has little basis in fact.
 
It is FACT that PENNzoil mined their oil from PENNsylvania. It is also FACT that oil mined from PA is known for it's paraffin content. If you look up paraffin & crude oil in an encyclopedia it talks almost exclusively about oil fields in PA. Furthermore, it is FACT that Quaker State (Pennzoil is one-in-the-same) used to boast about its paraffin content right on the side of its container—that is of course until Joe Consumer learned that paraffin is fancy for WAX.


Still skeptical?/forums/images/graemlins/screwy.gif Here are a few quick internet encyclopedia searches:

1-"Crude oil from the Appalachian Basin (Pennsylvania Grade Crude Oil) contains a lot of wax and paraffin…other crude oil, such as that from Prudhoe Bay in Alaska, contain much less wax…"

2-"[The Appalachian field] region is part of what was once the most important oil fields in the United States…range in depth from 400 to 4000 feet and produce high-grade (Pennsylvania grade) paraffin rich oil…"
/forums/images/graemlins/deal.gif

Now you can keep putting WAX into your crankcase if you like, but I think I’ll stick to Castrol and Valvoline.
After all… “people who know use [something other than Quaker Cake, er uhhh] Valvoline”… yeah that’s it! /forums/images/graemlins/rolleyes.gif

Gosh Tim... I always feel like a pro after debating you.

I have noticed different hot oil pressure readings on my gauge in my vehicles also when using a different brand of oil--one customer with a corvette bought some valvoline 10-30 for his car,he claimed the oil pressure dropped to 10psi after a trip on the highway--he complained loud enough for ny boss to give him 5 qts.of Amalie 10w-30(what he had always used in the past)and he showed us a half hour later how his gauge would not drop below 20 psi with the Amalie oil!.Must be different oils dont always have the same viscosity when hot--like Castrol,always bragging about having the "lowest thermal breakdown"of most oils. /forums/images/graemlins/dunno.gif
 
I've always heard of Castrol GTX and the such being the best oil out there...


Although who am I to say.

When my old engine was going out, I bought dollar store oil! /forums/images/graemlins/yikes.gif
Later, when I had to limp it to the shop, I took my girlfriend's rotten oil from the change I did for her, and dumped it in. Lotta miles! /forums/images/graemlins/deal.gif
 
I like Castrol oil,but havent used it since I havent been working a real job--its too pricey for me,when you can buy the "bargain"brand right next to it for half the price--I figure if the cheaper stuff still has the "SJ"rating making it good enough for a 2004 vehicle,its good enough for my old wrecks,especially since I change it every 3000 miles with a new filter every time.
I have a friend with an oldsmobile with a 307 from a 68 chevy 4x4 in it--it leaks like a seive from the timing cover seal--he's poor too,so he just keeps adding oil,since its not a mint motor he's been filling it with my old oil drained from my trucks,and from a friends repair shop--he changes the filter once a month,hasnt had any problems yet!.
When my dad worked for the gas company,they tried changing only the filter on one of their fleet cars,only adding a quart of oil to top it off--they were curious if it was really nessasary to change the oil and filter so often on a flett of 100 cars and trucks,so they decided they would try this on one car--it went 125,000 miles that way,one of his friends who also worked there bought the car for personal use when they decided it was time to trade it--he drove it four more years doing only the filter changes and adding a quart--makes me wonder if its worth changing the oil sometimes!--the car was an old dodge dart station wagon with a slant six,so it might not have been a good test--those things never seem to die anyway,even if you run them dry!--must be why mopar doesnt make them anymore,it must have been TOO rugged! /forums/images/graemlins/ignore.gif

Pressure is resistance to flow. Just keep that in mind.

Before I knew any beter, I would run 20w-50 in my little '84 Pontiac Sunbird (1.8 Turbo, EFI) There were times when I would start it up and get an oil light not from low oil pressure, but from high oil pressure. I'm gonna have to say it, but as Tim says (in a round-a-bout way) high pressure doesn't necessarily mean good flow. So you can't always measure the value of oil by your oil pressure gauge.

As far as oil change intervals, My T/A has an oil change light and according to the manual it comes on around 5-7k miles, depending oil pressure and crank shaft revolutions. It doesn't recommend changing the oil untill the light comes on. The filter, however, is supposed to be changed no later than 3k miles--sooner in severe driving.

My mother had a Grand Am ('80-something) and never changed the oil (or filter). She owned the car from about 40k miles to well over 100k miles before the motor went. I know several people who say the rarely, if ever change their oil.

I change mine every 3-7k.... think of it as cheap youth serium for your motor.

Oh, and hey Tim... I was dissapointed to see that i didn't get a direct response from you... /forums/images/graemlins/frown.gif /forums/images/graemlins/ears.gif

I didn't reply because I agreed with you. We're pretty much expanding on the same topics.

Humm, I remember taking apart a 350 (Chevy) engine that had used Penzoil since new. This engine had 1/2" of yellow sludge in the pan & valve covers. Penzoil always has & always will be crap oil! /forums/images/graemlins/thinking.gif

I have to agree, Tim is sharp! But I think he comes on a little strong sometimes, by telling a newbie to do a search. Maybe the guy did, maybe he didn't understand how to do it. And sometimes a search doesn't bring up a answer to the particular problem.

I'm sure Amsoil is great oil and their research top notch. I just wouldn't run their 20w-50. Keep in mind they are in business make money. I suspect they made a 20w-50 to fill a demand because there are many people who don't buy synthetic oil because they aren't commonly offered in a heavier weight.

Mobil 1 has produced a 20w50 for as long as I can remember Mobil 1 being on shelves. 20w50 is a very popular weight for those who run race engines.

Somewhere along the line I remember seeing an article where Castrol oil has one of the highest ash contents...
