Eric, Like most of the Oil filter vendors they bid on the contract as long as they meet specification for the cars. Purflux won. That's why it was used. Does that mean others are bad, no it just means that others didn't want to go as cheap on the bid. It's also good advertisement at a very little cost. In a general since all oil filters are good. When was the last time if ever you heard of a filter disabling a car. Yes, there will be some, but out of the millions and millions sold it's very little. The reason I like Bosch is that I can get specifications as to the lb's of by-pass and yes it has anti drainback, It has a strong steel case and has ample media to do the job. It's also priced right and easy to get. Purflux is not as you know. Is it a good filter, yes. But is it the best, toss a coin. As you and others know that another vendor bought a ton of them and had to promote them as the best and the only thing that would work in the DeLorean and I was bad news in selling Bosch. Now they sell Bosch and won't even order Purflux like you did and as I. I now have Purflux in stock. Trying to take care of the DeLorean customer.

Bosch I know this topic has been around a long time but I can't seem to find a definitive answer and reason. What filter is the best and why? I have heard the purflux does not have an anti drain back valve or a bypass valve. I have also heard that it does have these but that they are weaker than the bosch. I would just like to know (price aside) what filter is better and what makes that filter better? Another question, I recently bought two Peugeot oil filters from France. The numbers on the filters are 1109.45 and the numbers on the box are crossed out and now read 1109.78. When I look at the purflux web site I see that both those numbers cross ref. to the purflux LS410C. The filter is a dark blue with yellow print. They do have the chevron style filter element. Can anyone tell me more about these filters? Are they of any historical significance? Would they be allowed in concours events? Last question, do oil filters go bad? Is there any reason to be concerned with an oil filter that has sat unused on the shelf for a long time? Will the rubber seal go bad? Will the filter element become brittle and possibly separate thus causing damage to the engine? I appreciate any information on these topics. I am sorry to bring it up again. I am sure everyone is tired of talking about it.
