Whilst filters can trap smaller particles as they clog, the flow rate reduces. Its a no-win scenario.
Except that the new filter if of suitable quality is designed and capable of trapping the size of particulate necessary, as such they perform as they should straight out of the box. A new filter has much more capacity for particulates than a clogged one. A new filter does not inhibit flow. Just a few reasons why this 'old filter is best' myth is just more 'pub/forum talk'. There is some truth there, but the reality has been somewhat skewed. |

27 to 714800 miles
245 GL 1989 1986cc CI (constant injection) converted to LPG at 151k.
This engine went to 500k where the cylinder pressure went down 11 bar. Volvo minimum 9 bar. It was slowing down, too slow to tow the caravan, but was still doing 5k ltr of oil. Now a used 2326cc from Braydon Motors London for £265 while another 2.3ltr is being rebuilt, this cost £150 for ebay. The 2ltr could not be bored out as it would break through to the water ways. Shame! In order in my opinion what matters. 1. Very clean oil always. This is achieved with by-pass oil filtration. The ordinary full flow filters to 16 micron. At quarter flow the larger by-pass filters to 2 micron. Interference at the piston ring and bore interface is 6 micron. Herein I think lies the secret to long life. Before you change the oil you send a sample to the North Wales Laboratory for a detailed analysis, this tells you change or go to the next service period. A detailed report picks up fuel, coolant, and all the metal wear rates. Generally, my change rates for the 2ltr engine was 70k. Once it was 150k. 2 LPG is clean fuel little carbon gets into the oil. No particulates, no NOX. Current cost 59.9ppl. TfL seem happy with this to. Conversion paid for its self in 2 years, but only petrol engines with hard heads will last. 3. Engine preheaters. I had the Kenlowe original but was not as reliable as the Volvo engine. There was a modification to switch on the cab heater fan when up to temperature. Hard work though. 4. Quality 0/30 fully synthetic oil. 5. Often thought a filter system on the gear box would be good as the my M47 gearbox started bulking at 5k miles. bobistheoilguy is a good place to get information. Regular maintenance of course. Garages don't like bypass filters. BrianH 800 to 1000mls a week |

The by pass oil filtration system went out in the late 1950's , why would you not want all your oil going through the filter?

I appear to be the only person thinking this but here goes:
Regular high mileage should allow you to increase the time between oil changes, the oil is hot for longer and not under stress so will last longer. Thinking back to 1990's BMW's and the company I worked at had 4 or 5 BM's with the famous 'countdown' service indicator lights. The car's computer would monitor the number of starts/mileage/oil temperature and vary the oil change time to suit. Some of the high miles guys would get over 30,000 miles whereas the 'town' drivers would be 12,000 ish....

Over the next 9 years I'm sure they regretted that attitude given the number of bits that had to be renewed including the turbo. Still it was and is their van, now written off because it needed an oxygen sensor which exceeded the spend limit. The next owner will inherate headaches. Paul. |

Computers!!! and their algorithms
These computers are set up by the manufacturers. The main agents pay thousands of pounds for them and we believe them totally, don't we?
With my experience with my wife's Polo:'nothing is wrong Sir', £60 please, but she wouldn't drive it in limp mode at 20mph. What do these garages know about electronics? My laptop computer often gets confused and needs cleaning. Manufacturers need to support Main Dealers, but you pay the premium. On board computers are increasing, exponentially. Where is this leading? Boredom is worth it, think H&S. Less deadly mistakes on the road, and of course this is essential. I digress, very clean oil is the answer to long life in my opinion I have evidence. Currently I deal with Don at Performance Oils. He stocks all the items I use and I have sent him a spreadsheet of the B200E engine performance from 150k to 497k by using the bypass filtration and his 0-30 Amsoil. In the spare engine I am currently using a 5-30 fully synthetic from Tesco, as it is API L or M standard. Being lazy, not changed it for 100k, and now at 200k from installation, as I await the rebuild engine (2k pl). Special offer £6 for 2ltrs. ( Said to have 165k on the engine when purchased). Go for the facts not the myths. BrianH 715326k |
