car10001 52 Posted May 23, 2018 hi if youre not likely to have the ef much longer, can you just change the oil and leave the filter for now and keep running it to rinse the old oil and if you still got it in a few months then change the oil and filter or swap the engine and put new oil and filter in it thanks Share this post Link to post Share on other sites

car10001 52 Posted May 23, 2018 what happens if you leave the filter this time and do another oil change in a couple months if you still got the ef then do oil and filter or swap engine and put fresh oil and filter then Share this post Link to post Share on other sites
hendrixhc 10,918 Posted May 23, 2018 easily found on google  Dirty or clogged oil filters allow contaminants to sail straight to your engine where they can cause damage as well as affect fuel economy. You also risk blocking the flow of oil to your engine, which could result in engine failure. Protect your engine with a fresh oil filter, replaced every time you change your oil. 2 Outback Jack and bear351c reacted to this Share this post Link to post Share on other sites
Mr Polson 10,214 Posted May 23, 2018 If you're not going to change the filter, don't bother changing the oil. Once the filter is dirty, it cant hold anymore contaminants, and will either clog up and cause low oil pressure or allow the contaminants back through the motor, meaning its not doing its job.

SPArKy_Dave 8,831 Posted May 23, 2018 YES, change the filter. For $10 or less, it's worth it. 1 Outback Jack reacted to this Share this post Link to post Share on other sites
gerg 10,871 Posted May 23, 2018 If it's about the cost of the filter itself, that's a no-brainer. If it's about having the ability to do it (lack of tools, time, mobility, etc) then that's a different story.I'm going to be completely contrary to everyone else here and say that the oil itself is more important than the filter. Here's why:- The size of the paper element inside is a couple of metres long. It would take a long time to clog that much surface area.- In the case of air filters, manufacturers actually advise not to change them as a matter of course, because over time, the filter becomes more effective at filtering as it "blocks up". Hence why trucks (and some cars) have filter minders to tell you when to change it. Oil filters would be exactly the same in concept.- most contaminants stay suspended in the oil itself (ie fuel, carbon, moisture), so changing it would eliminate that aspect.Anyway, it's best practise to change the filter, but if you ask me, if you really have to, you could skip it every second oil change and not worry about it.Sent from my CPH1607 using Tapatalk 1 deankxf reacted to this Share this post Link to post Share on other sites
