First link says: If you’re wondering how often you should change your oil filter, keep things simple by changing your oil filter every time you change your engine oil. Following this schedule might cost you more money, but it will save your engine from possibly getting clogged with grime, sludge or large metallic pieces. Second link says: Many manufacturers say to change the oil filter every other oil change. So, if your owner’s manual calls for oil changes every 7,500 miles, that would be an oil filter change every 15,000 miles. But a lot of owners and mechanics — many of them the same people who would never go past 3,000 miles per oil change — also would never dream of doing an oil change without also changing the filter. Their reasoning: Why pass brand-new, clean oil through a filter that’s already carrying gunk from the old, dirty oil? I just follow my manual that says every change. If yours differs, fine, follow it. |

> I don't disagree on having your oil sent out after the fact for testing. Different situation but when I was driving the standard was 12,000 miles or about once a month. At 10 gallons or Rotella and two or three filters, that adds up. When the older trucks were being replaced with Volvo Whites with the Detroit 60 engines, the shop foreman started a testing protocol.The tests showed no significant degradation at 20,000 miles but that became the new standard. When I asked him his reply was the oil had to be changed sometime and 20,000 seemed like a reasonable target. The Detroit 60's were game changers. A lot of them were hitting a million miles without an in-frame rebuild. Previously most big diesels were tired at about 700,000. |

That's why I said it's OK whatever schedule others used. Alls I said was the manufacturers often recommend every other interval. Those who refuted that fact didn't produce a single reference. I produced five. Alls I'm saying is you can replace your filter on any schedule you like. But don't claim manufacturers don't recommend every other oil change. Everyone who claimed that so far has pulled it out of their asses. That's all I'm saying. You do what you want. I do what I want. I follow what the manufacturer recommends. (1) I choose good oil (lasts longer than the manufacturers recommendation) (2) I choose good filters (they last longer than the oil change interval) > Second link says: > Many manufacturers say to change the oil filter every other oil change. Of course it says that. It says what I said it said even though some dufus said it didn't say that. Alls people are doing is pulling out recommendations from their own ass. Nobody but me has supplied any references from manufacturers & manuals. You do what you want to do. I will continue to follow the manufacturers recommendation. And I will continue to choose the best oil and oil filters I can figure out. The only thing new to me is the huge number of synthetic oil specs. I don't know how to choose a good synthetic oil yet. There are too many specs to try to figure out at this point. ACEA A1/B1, A5/B5, A3/B4 A5/B5-10, A5/B5-12 API SN, SN Plus, SN-RC, SM, SL, SP BMW LL-01, LL-04 Chrysler MS 6395 FIAT 9.55535-H2, FIAT 9.55535-M2, FIAT 9.55535-N2 Ford WSS-M2C153-H, WSS-M2C929-A, WSS-M2C930-A, WSS-M2C945-A, WSS-M2C946-A, WSS-M2C947-A GM-Opel LL B-025 GM 4718M, 6094M, LL-A-025, dexos1 Gen 2, Gen 3 Honda HTO-06 ILSAC GF-5, GF-4, GF-3 MB-Approval 229.5 Porsche A40 Renault RN0700, RN0710 VW 502 00 - 505 00 > many of them the same people who would never go past 3,000 miles > would never dream of doing an oil change without also changing the filter. Like I said many times before you do what you want to do with your oil. But don't tell me my references don't say what I knows they say. I didn't post the references without reading them first. You alls pulled out everything you said from your own asses. > Why pass brand-new, clean oil through That's OK. But what you pulled out of your asses is not what my manuals say. > I just follow my manual that says every change. > If yours differs, fine, follow it. Just don't tell me my service manual don't say what I knows it says. Everything most of you said you pulled out of your asses. I'm not a believer in bull**** as you can probably tell by now. Yet I'm new to buying synthetic at ~$2.50/qt so alls I want to know now is how to tell the difference for sure between any two synthetics. Does anyone here know how to tell one synthetic from another? |

To your point I was a Detroit owner until I bought my first Japanese sedan. Had a few German sedans in between but Japanese models never broke on me. As I age I don't have time for Detroit garbage nor even German complexity. What I need now that I'm shifting from conventional to synthetic is a good way to tell the quality of any two oils from just the packages in my hands. As you can tell by now I don't get my facts out of my ass so I'm willingly admitting openly that I don't yet know how to compare any two synthetics. Do you? Does anyone? How? |

No, but I often drive older cars with tappet bearings, and that includes my daily driver. Oils formulated for diesel engines are likely closer to the oil they were originally designed for, however. >> The base oil gets better, but the additive package changes in ways that >> may or may not be an improvement depending on your requirements. > >Does your gasoline engine vehicle have a modern cat? >Does your state do periodic smog inspections on that vehicle with a cat?

Same way you compare any two oils. Viscosity breakdown with time, viscosity curve with temperature, adhesion, solvent characteristics, ability to keep particulates in solution, three-ball test, etc. There are standards for all this stuff and in general the European standards are tighter than the US ones. It's interesting to look across a given line... for example, the Castrol Syntec 10W-40 meets the latest European standards but the 10W-30 and 10W-50 formulations do not. --scott -- "C'est un Nagra.
