Previously I've used Wix filters, but quit when they started having the thread problems. It always took 4 1/2 quarts to fill the oil up.

Now I'm using Pureone from Purolator. Thread on nice and easy. But today I put exactly four quarts in after an overnight drain of the sump.

The oil level shows it to be maybe a pint high. Anyone else notice this? I know the Wix was larger, but it don't look to be THAT large!

Kind of odd, I'm thinking. smiling bouncing smiley

This car is now very nearly completely done. Sure to find something else, but not now.........And 12 years later, I'm starting to fix things that were new when we built the car. It's pretty well de-bugged!

You have run the engine to get the oil circulating before checking the level?

When my engine is dead cold for a few days my oil level will read around the "M" on "Max".

I thought that it was the NAPA Gold filters which had the thread problems; there are two sizes of Wix. Maybe you had the big boy.

This may not help, but at least it's a data point for your comparison.

When I was using NAPA Gold filters, it took exactly 4 quarts to reach the full mark on the dipstick. I switched to the Purolator 20195 and it still takes exactly 4 quarts to fill. And that's with an oil cooler.

In any debate, the side which strays from civil discussion is usually the side that lacks confidence in its debate position or in the merit of their arguments. Making personal attacks on the opponents instead of staying on the subject is also a sign of weakness.

Anyone who feels compelled to respond in kind to any perceived slight is often suffering from narcissism.

First, I did run the car after filling the oil. The water pump had gotten real noisy, (didn't leak, but it would have soon) so I changed that out today. I ran it for two minutes dry to seat the bushing, and then for about 10 minutes after the coolant was in it. So the filter is full.

And after an hour or so of sitting, the oil is on the "A" in max. Strange.

Chris, I think the NAPA and the Wix are the same filter. And I am now using the Purolator 20195. No oil cooler.

Still dunno, guess I won't lose any sleep over it. Moving on to the Pertronix ignition now!smiling bouncing smiley

NAPA is made by Wix, but IIRC only the Napa filters had the issue. I'm replacing the water pump in the TR6 today. Hmmm.

Interested in getting rid of the TR-6? Had any ideas of a 4.3 litre MGB with an automatic trans? devil smiley

Good to see you around again, my friend!

Wayne,

I am still using the WIX 51068 oil filters without issue. I have found that the initial fill is exactly 4 quarts. However, after starting and running I find that a have to add an additional half quart. I have always assumed the filter anti flow back valve holds some of the oil from returning to the sump.

Don't think it hurts anything to put 4 quarts in, but mine takes 3 quarts and 20 ounces to fill to max (no oil cooler). That's with a 74 engine and oil pan and a Purolator filter (filled).

Well, it's still a curiosity to me! Anyway, moving on now. But I now know to only put in four quarts.

I use a 3/4" cap screw to check the thread on any filter I stick on the car. Have found some that were a bit too tight for my liking, don;t remember brand. But I don't "stock" NAPA filters when i can get Wix and others for less $
