You have to buy TK7 direct, and in case quantities. A case is good for 500-1000 gallons of gas, so it's really a great deal. Its a superior product for the same price as the junk additives at the parts stores.

In my area, Fram, AC Delco, Purolator, Wix, and ST at Walmart are the dominant filters. There are probably a hundred or more brands out there. Anyone have a complete list?

Yeah it ticked me off when Wallyworld stopped stocking the AC Delco. I really like that filter, along with Purolators. Now I'm trying out ST and they seem to be OK as far as startup noise is concerned.

This is a great idea! Question: Are all types of filters for a given engine built the same basic way? For example, my 406 Chevy uses a AC Delco PF25(I dont use fram ). Would all other brands like ST, Wix, Purolator, etc. be designed the same?

Thats the 3rd post about the same recall. I have nothing against Coastal. In fact, thats all I use in my differentials, along with a dose of their limited slip additive.

At what mileage should a UOA be done? At oil change? At a certain mileage? I see guys doing it at very different intervals and was wondering which would give me the best overall indication of the condition of the motor. It only has around 5000 miles on it after my rebuild. Should I wait a little...

My Walmart only stocks 15W-40 Delo and Delvac oils. Walmart is the only place I buy oil. The auto parts stores are too high and most dont carry much if any diesel oils.

Well, I stocked up good on the Chevron Supreme 5W-30 Sunday. Now I have a question for you fellow oil gurus. Does Chevron market a synthetic blend oil? If so, where is my best bet to find it? I didn't notice it at Walmart, but they were low on their oil stock that day. I wouldn't mind paying...

Like I said before, the QS 10/250,000 deal is mostly marketing. How long do you think you will have to pull teeth to get them to pay up?

Uh, newbie here. This is way over my head carry on

I've found out that Chevron and Havoline are the deal of the century. They actually say on the back of the bottle that it is group II.

Is this true?? How many hoops do you have to jump through to get that deal?

The ST is a quality filter. I just bought several at Walmart today, along with 2 cases of Chevron Supreme The ST30 my small block takes does have METAL endcaps! Looks about the same inside as the Purolator I have been using for years.

So I assume there is no 30 weight types of diesel oil? I am a big fan of 30 weight oils. My oil pressure is already plenty high and I dont really want to go to a 40 weight oil.

For the price you can change it twice as often...piece of mind. I'm not a big fan of long drain intervals, regardless of oil. Thats just too long for stuff to run through the engine.

Car Craft got 18 hp on the engine dyno going from 20W-50 dino to 5W-30 synthetic. That's a crock in my opinion. The only way I see an 18 hp gain is if they originally had 80W90 gear lube in it

BG44K was THE stuff in the late '80s and early '90s. I used to work at a Datsun repair shop and thats all we used. It worked great as long as the car didn't have a "terminal" injector problem.

I knew from the Chevron site that it was based on group II, but I was wondering what IsoSyn was. Maybe an additive package or a dose of group III mixed in?

Yeah you guys are right. Brain fart! It did say for gas engines also, so I guess its cat safe. And 15W40 seems to be the popular weight. I only use 5W-30, maybe 10W-30 in the summer sometimes. I have read on here that 40 weights break down quicker, but maybe the Delo and Delvac oils are more...

I thought $1.77 was CHEAP! It's only 40 cent more than the Motorcraft dyno juice. Quite a deal in my book. And you are right, I was thinking wrong. The ST is $1.63 for the synthetic blend.
