Step, thanks for the link to that great oil filter article! You've alerted one more former Fram fan to the evil which lurks in the pretty orange can... I'll just use that neat grippy surface on my Fram to remove it for the last time!

I always use mopar filters on my engines slant,440,318,etc..I have never had any problems.

Mopar branded filters are generally not very good either. I use Wix, Purolator and occasionally Baldwin. I wouldn't use Fram or Mopar unless I had no other choice.

Unless things have changed Pennzoil and Quaker State are parafin based oils. I had a layer of goo in my oil pan on the Duster with a Pennzoil sticker on the door.

Carquest, and NAPA are Valvoline. All I have used in my van motor in that hot engine box pulling a lot of weight. (6000+lbs) I pulled the heads at 125K and the engine was as clean as the day I built it. I used Fram on it when I first built it. I had a rod knock on start up, and low oil pressure according to the factory gauge. Got the info on Fram and went to the Pure1 ever since. Rod knock went away!

Havoline used to be the nastiest smelling oil ever! Back in the 70's it had a high ash content. I won't buy anything Texaco for that and another reason.

1. Things have changed.
2. The "paraffin base = sludge" idea that won't die is based on a faulty understanding of the word "paraffin". It's a word with many applications. Most Americans picture bars of white wax (or candles) when they hear the word "paraffin". Most Brits, on the other hand, think of what Americans call "kerosene". Both applications of the word are accurate.

Too many people who were born on third base actually believe they've hit a triple.

The goo may have been due to infrequent oil changes. I used Pennz forever and didn't have buildup issues. A friend of mine uses Pennz, and has a '69 Mach 1 (since early 70s) When he tore his engine down with 120k miles on it (during restoration), it looked like new inside and had little meaurable wear. I think most brand name oils are ok, as long as you can get enough zinc for flat tappets, and you change it often.
