after checking casting/index numbers on an older 350 4 bolt chevy motor, i see the block is a 1980.
With all the conflicting reports, anyone know what would be the best oil filter to use? I was going to go with fram, or stp, but have seen negatives on them. Engine doesn't leak oil, so i'm also considering changing to castrol synthetic 10x30 oil (?). I'm "told' the rebuilt motor doesn't have but a couple thousand miles on it. Street rod (36 chevy 5 window coupe) and although i'll turn it loose from time to time, the car won't be raced. Thanks.

Wix or Napa gold, is what I hear/read..

 

Wix makes Napa Gold filters, same assembly line but they don't make the lesser quality Napa filters.

 

No way FRAM ! AC/Delco it is a GM motor after all.

 

New AC/Delco filters are crap. They are made in Mexico and quality has gone down. The end cap is now a thin stamped piece of sheet metal with a few spot welds. I switched to NAPA Gold/Wix exclusively a few years ago when this happened.

 

I'm using Royal Purple and Moroso oil filters now. The reviews are good so far, but will give the NAPA gold a try if they have them in the length I like.

 

i am using a WIX 51794 on my 1962 Chevrolet Bel Air 327/300 with a adapter. I fill the filter with oil before installing it because it has a 2 quart capacity (7.82" long).
It takes too long for the engine to fill the long filter if you install that filter empty.

WIX. 51069. 3/4 quart capacity
WIX. 51061. 1 quart capacity
WIX. 51794. 2 quarts capacity

 

If your engine has a flat tappet cam I'd be more concerned with using oil with enough ZDDP

I use the Mobil 1 filters, they're pricey but I mean, usually our rides get driven so little, an oil change is usually only a bi-annual expense

 

x2 fill the filter with it off the car..
and
Part number 51060
A 1 quart filter. Is the same as the 51061 above except has an anti-drainback valve (this is not a bypass valve). Size is still 5.18 inches high.

 

On GM engines, you don't need a oil filter drain back valve. The oil filter is mounted vertically.

On GM engines, you don't need a oil filter by-pass. The engine block has a built in by-pass in case the filter becomes clogged or the engine RPM exceeds the flow capacity of the filter.

 

A/C Delco filters seem to be less expensive than Fram these days..

I switched from purely Napa Gold to whatever except Fram, Namely Purolator... I have been tempted to buy a service case of Parts Masters which is a cheaper brand that Wix makes. for my daily drivers since the price each would be about $2.20 given all the cars I service take the same filter

 

Using Moroso Racing filter on my SBC powered 48 Plymouth. Recommended by the engine builder (Jensen's Engine Technologies). I trust his opinion.:thumbup:

 

I think Bob the Oil Guy has done an extensive oil filter study.

There is no way I'd cheap out on an oil filter. I've used NAPA Gold on my diesel truck (400k) miles and my Willys Streetrod (20k) miles.

Cummings will void warrantee if non approved filters are used. Fleetgard recommended but WIX is acceptable.

I once blew two "F. " filters off my fuel funnycar in the pits.dumping 12 qts of 70 weight all over the parking lot. We usually got free "race filters" if we ran their stickers.

I removed the filters from the circuit and ran without for the day. No problems also removed the stickers and wrapped them with mess at the trash can. It did change my thinking on the oil system.

 

I've pretty much stuck with Wix and have had no problems. I think NAPA and CARQUEST are made by Wix also. I understand that filters that pick up the smallest microns 10-12 will block quickly and start to bypass on high volume, high pressure pump engines using race weight oil. Frankly I grew up on Havoline with 2k changes and I can't remember an oil related problem or opening up a dirty engine.

 

I think NAPA and CARQUEST are made by Wix also.

As noted above, NAPA Gold filters are made by Wix. Regular NAPA filters are not.

 

Carquest filters are no longer made by WIX/ Affinia. Just like their belts and hoses are no longer Gates, they are Dayco.. I think their filters are Champion labs filters which isn't a bad line, never was but has been owned by Fram/ Honeywell since 2012 I think

 

If you guys cut open and inspect your filters you will quickly see the differences and why cheap filters are problematic. Example, Cardboard instead of a metal shell holding the filtering media. The WIX seems to have more pleats and filtering media than many others.

 

I've used napa gold for new engines breakin and been happy. I'd also be confident with Wix.


For all my daily drivers as well as the racers I've stuck with the Purolator Pure-One filters. They even have ones specifically for synthetic oils which equals out the added mileage gained with them (meaning extended change intervals with synthetic is great but the filter must be accounted for in the extension too). With some of my race engines being in the mid-5 figure cost ranges I've paid close attention to filters over the years.


The PureOne filters have been consistent in so many 3rd party tests and evaluations that it has me convinced of the quality. They are almost always near the top of tests. BITOG Has a lot of tests and feedback too and the same there - good reports and consistent from many sources.


Purolator: Nothing Gets By Us.


And while I don't like to support companies that get too big, Amazon is an easy place to get them (can't find them at the local parts stores where I am). I use the PureOne but they have a new one called BOSS that appears to be even better. Almost double the dirt removal capacity (pureone = 15g and 10K mile life / BOSS = 27g and 15k mile life).


Anyway, that's my experience and what I use on all my vehicles.

 

Wix and K&N, Fram went down the toilet a long time ago.

 

The company that makes Fram filters chose to go for the high -volume, low-ball market. They want to sell their products at discount stores and quick oil change establishments. People that buy oil change products at those locations care more about saving a few dollars rather than spending more for good performance.

 

WIX,on all my SBC"s.

 

Usually WIX or Purolator on my '31 with a SB Ford though a Motorcraft if I can find a short one locally. On the DD and the 6.7 Ford diesel truck, only Motorcraft to ensure the extended warranty on both isn't ever questioned (plus they are a top of the line product)

 

Interesting.....I might have to look into the Boss for some of my vehicles, that are DD on the synthetic...they list "Advanced" for my '15 Camaro, Im assuming that's a PureOne filter?

 

Not sure how new the BOSS ones are. I haven't seen them around retail yet so maybe they are very new. I've been using the blue pureones for the synthetics.

 

i've posted this before:

an experience with NAPA filters back in the 1980's when I ran my mobile service -repair bizness.

I picked up my oil filter order. I used the gold NAPA filters on several accounts. The store was short, and gave me the standard filters for a couple Gold label numbers.

Being an anal guy, I opened both boxes Gold & regular filter to compare.

On the bottom of the canister was the ID number printing. Both filters had the Same numbers. The sales guy tells me that just indentifies the filter for boxing and to ID later if needed.

i looked at him and said: um, that is my point. One filter is near 2 dollars more, yet the same ID numbers printed. Why?

I never received a proper answer from anyone in NAPA

 

New Delco filters are bunk. The Ecore technology isn't good.

Avoid the cheap Fram Extraguard filters. It uses a nitrile anti drainback valve and a 37 pleat filter.
Their Ultra filter is much better. It physically weighs much more due to the extra filtration material. It uses a silicone ADBV which is much more pliable. It has a 47 pleat filter media that is of a much higher quality than the Extra Guard.

A buddy of mine did a personal tour of frams R&D facility and was very impressed with it. He talks with the same folks every year at SEMA.

ALL SBC/BBC's use an oil bypass p/n 25013759 which starts to bypass when more than 11psi of oil pressure differential is applied across the filter media. This can occur when the oil is still thick and when the engine is revved quickly.
All SBC/BBC's call for a full flow oil filter that has NO internal oil bypass feature.
A 30 psi oil bypass is used in engines equipped with a factory oil cooler. If there is a pressure differential greater than 30 psi across the cooler(ie when its clogged) the oil will bypass around the filter. Oil bypass for the coolers is p/n 25161284
