Has anybody installed a bypass oil filter on their vehicle? If so, how long until the first full oil change? What criteria do you use to decide when to change the oil without doing an oil analysis? Ive installed an Australian designed filter (Jackmaster) and changed the filter roll at about 10,000Km and just topped up with about 1/2 liter of oil. So far, I've used 6 rolls and would have continued the same regime but my wife serviced the car and forgot to say 'no oil change'.
Any suggestions welcome - not about the wife thank you!

Hi Robbo123,
Regardless of whether or not you have a bypass filter installed, you will still need to change your oil at regular intervals. The extra filtration is a good idea but it wont actually extend yor oil life. The oil in a car engine runs very hot

I knew a bloke years ago who never changed his oil. Instead, he topped up when required, and he regularly changed the filter. He explained that the oil gets dirty and changing the filter fixes this. The oil molecules break down and burn off and topping up

Thank you for the advice - much appreciated. My car is about 18 years old with the original motor and is not butning oil so Ill keep testing the bypass oil filter to satisfy my own curiosity. I have just recently read a research report from the USA Depart

The trouble with using a bypass filter and not changing the oil is that the filter will not remove acids from the oil.
Petrol is an acid and as such the oil becomes more acidic over time and will eat your bearings. This is why you should put fresh o |

Just had a look at bobistheoilguy.com - a great site for info on oil. The engine oil does become more acidic over time but the damage appears to be more of a problem when condensation (water) dissolves any soluble acidic compounds. Fortunately, my bypass

I used a bypass filter for many years on various cars.The filter was made in Perth and was called a 4M filter. I dont think they make them any more. The longest use was on a 69 Fairlane 302 V8 which I did over 200,000 miles in without an oil change. I dro

Thanks Jim. I did search the web and found many oil recycling sites. What they say is that the "base oil" does not wear out and can be recovered. Its the additives that are depleted. Apparently, when you use the bypass oil filter much of the dirt, metal p
