If they are diesel engines . Do not put bio-diesel into a gasoline engine as it will ruin it.
I think you’ll quickly discover that small automobile diesels are exceedingly finicky in the matter of fuel, and that the warranties on the fuel system are voided when you use anything but approved fuels, one of which is not home-made bio-diesel.
Apparently someone must be out there selling bio-diesel digester setups and telling everyone that they can run any car with the product. Bio-diesel is a more practical proposition for large diesels of the sort used for power generation, ship and large truck propulsion, and perhaps some aircraft and construction equipment.
Any diesel engine will run on bio-diesel. The fuel filter will need to be changed after the first 1000-1500 miles of bio-diesel use. This is due to the fuel cleaning out the engine, and all the dirt being caught by the filter. Once this has been done, the filter should be changed every service (as normal).
What to do in winter depends upon the type of oil you are processing, and your global location. In the UK, for example, it is best to avoid palm oil alltogether, and to mix 50/50 diesel/bio-diesel over the colder months.
No modification is required for diesel engines to run on bio-diesel. You may, on older vehicles, need to change any natural rubber pipes/hoses/seals to synthetic rubber (this should have been done in the last 11 years anyway!) Modification is required, however, for neat vegetable oil- hence an element of confusion amongst some people.
Old VW and Mercs definitely run on Bio-diesel- a friend of mine runs his 8year old VW Golf on 80%, and Mercedes warranty their vehicles for bio-diesel in Switzerland.
Hope all that helps.
