were there any cars that came with a factory bypass or centrifugal setup?
Any factory cars ever come with a cent. or bypass?

All my MB diesels came from the factory with a bypass as part of the filtration setup.
The bypass filter section is mainly filled with cotton gin waste.

The old mid-80's Ford Escort and Tempo cars with Mazda diesels in them had a filter mount that had both a full-flow and a bypass filter, mounted opposite (above/below) each other. What a messy PITB to change. I had two; 1986 Tempo and 1987 Escort.
Hi Dave. The vintage 356/912 air-cooled Porsche's had the by-pass filter mounted to the fan shroud. Is that the type you were referring too?

My variant of the the OM906LA 6.37L 6 cyl midrange diesel in our Unimog - the 902.912 - came from the factory with a centrifugal bypass unit because it had EGR, now removed.
The factory recommendation for OCI for the non EGR version of this motor, without centrifuge, using MB228.5 oil, is 1200 hrs.
What would it be with a centrifuge? 1500, 2000 hrs?
The engine consumes 1L of oil every 64 hrs so in 1200 hrs I'd replace 18-19L out of a 29.6L sump capacity.
The longest I've gone is 22000 miles/600 hrs/1.5 yrs/10L makeup, but I had to use some different makeup oil (still 228.5). Unfortunately I changed it on a farm and didn't get a UOA.

Land Rover Discovery TD5 has a normal oil filter (cartridge) and a Centrifuge type filter, which also has a removable element.
All vehicles manufactured prior to about 1955 that had oil filters installed used bypass filters.
I don't remember the details but there was a taxi cab company that had Frantz bypass oil filters factory installed on all their new cars. I believe that was in the late 1960's or early 1970's.

A few years ago some Ford trucks and motorhome chassis came with a NTZ bypass filter on the transmission cooler lines.
Hi,
daves66nova - In past times a number of vehicles (cars/trucks) were factory fitted with by-pass filters. With cars, cartridge/canister type FF filters replaced them several decades ago as engine technologies progressed and improved
Simca (France) was but one car manufacturer who used a centrifuge. The Simca version was installed inside the harmonic balancer at the front of the crankshaft and was quite easy to clean
Heavy high speed diesel engines respond well to centrifuge by-pass filtration and a number of Manufacturers fit them

Just noticed your post on the 80s Fords with the 2.0 diesel. I also had two of them at the same time. A 1984 Tempo and a 85 Escort wagon. 45MPG town and 52 hwy.

Yup - very frugal. Even at speed. You could run 80mph and still get phenomenal mileage. Of course, it seemed to take a full calendar day to get up that velocity. They were very slow to accelerate; like molasses in winter ... Also quite reliable and known to put on many hundreds of thousands of miles, if well cared for.
I really wish the US industry had not walked away from small diesels so easily, but I certainly understand the market response; people didn't want them and they did not sell well. I would love to have a small 3 or 4 cyl turbo diesel car now, but I simply don't want the added expense and maintenance issues now prominent with the added manure of DPF, heavy EGR use, SCR DEF, etc.

Well blame the EPA, you can't get around it (legally). That said, I get over 50 mpg hwy in my 2012 Jetta 6 sp. 46 mpg average lifetime mixed driving and that is with a DPF and stock tune. This model does not have DEF however.
The cruze diesel is interesting but no 3 pedal option rules it out for me.

The thing about your post that does make me chuckle is that the US has historically been more inclined to have automatic vehicles
Europe and specifically the UK historically was more inclined to have manual
Now more and more in the UK are going to auto and you rule a car out due to no manual option
Strange how tastes change over time
The Cruze is available with manual in Europe though, but is only a bit player in the market as it is dynamically off the mark and there are many better options for the money.
This may change as they have brought out a much needed estate. Small saloon cars sell poorly in the UK
I always thought it was a nice looking car

Keep in mind your on an automotive enthusiast forum, so the percetage of forum goers that prefer manuals should be much higher than your average american.

Most of the Japanese small diesels from the '90's and 2000's came with a dual bypass and full flow filter in the one canister. They seem to be going to a what seems ridiculously small full flow filter on newer engines, but the Mitsi 4D56 which started life in the '80's is now a dohc common rail engine with double the hp and 3 times the torque, and still takes the dual filter.
The old Fiat 500, called the Bambina here had a centrifugal filter.
