However I do agree with Shipo, if you can use the 0w, you do get both a faster and better flow. If 0w30 were NOT at premium to 5w30, I would go to that viscosity in a heartbeat. My other issue (small) is less line item stockage, as well as less units on inventory. In my case to illustrate the point, would I rather stock one viscosity (0w20), and the next oil change (up to 7 qts); or would I rather stock 5w40, (5 qts), 5w30 (8 qts), 5w20 (4 qts), for a total of 17 qts. ?

Replying to: robert1955 (Oct 31, 2007 9:37 am) before the intrigue was traded for the torrent, it was in the shop to have the intake replaced. out intrigue had the 3800 engine and was prone to the manifold(composit material) warpping at the egr valve and letting coolant into the engine. when the tech had the engine apart he commented on how perfectly clean the inside of the engine was. i have a question for those here. what brand of oil filter do you use and recommend? i have used the mobil1 filters, but was wondering if there are better ones out there. thanks richard

Replying to: rhouser2 (Oct 31, 2007 4:14 pm) Short answer, using an example, OEM. Since almost all oil filters are vendored by someone else, OEM filters are made to OEM specifications. The Honda OEM Civic's oil filter is vendored by FRAM. (old Allied Systems) now owned by Honeywell. (flameproof suit on, SCBA at the ready) The Honda Civic OEM recommendation for engine oil filter change is "EVERY OTHER" So since the recommended oil change is at 10,000 miles, 5w20 (CONVENTIONAL oil) fill, every other is 20,000 miles engine (oil) FILTER change. (flameproof suit on, SCBA ON) Literally for my .02 cents, oem (FRAM in this case) AND the familar FRAM ORANGE model numbers are at premium to very well made, (CHAMPION LABS) WallyMart SuperTech filters at last purchase, $2.12 per oil filter. (flameproof suit on, SCBA ON-fire fight is ON) I change the Mobil One 0w20 AND filter  20,000 miles OCI's, because I am a conservative, belt and suspenders kind of guy!

Replying to: imidazol97 (Nov 01, 2007 7:02 am) The issues became starkly clear to me in that I use a so called OEM/vendor ed cartridge oil filter in a VW Jetta TDI. It is MADE to go a 30,000 mile OCI. (Made to support the VW 507.00 specification, the so called LL or long life oil (up to 30,000 miles) Short story shorter, I wish ALL my cars had 1. top access 2. cartridge type oil filters. As you can surmise, that is a a 1/3 over the OEM/vendor ed by FRAM- Honda Civic. MORE cents/dollars in a cartridge filter (CAN) be used to upgrade the filtration and/or charge less or both! . Contrast this with the normal spin on/off filter. The majority of the spin on/off parts are related to STRUCTURE and NOT filtration and this is no matter the cost. In both cases because of the fact the oil filter is designed to be an overflow valve, you can only get the particle filtration down so far before it tends to impeded high volume oil flow. Oxymoronically oil filters (as well as air filters) filter better slightly to moderately "used"!!?? So again, oxymoronically when the oil filter is functioning BEST is when it is most likely to be removed for a new one which does NOT FILTER AS WELL!!!!??? So filtration can be measured, compared and contrasted much more microscopically, so to speak with multiple and long term trend line UOA's. Yes indeed it does make logical sense, higher cost higher quality, but....Now the weird question : is it statistically correlated!!??? The answer is NO or at best unclear. So that I am being clear: if my car will last to say 250,000 miles with the "el crappo tsk, tsk" filter: with 4x better the cost (of the spin on/off oil filter) will my engine last 1 M miles? Do you see the disconnect here? Following the logic to another bottom line here: almost NO folks (% wise) use bypass oil filtration!!?? Aftermarket is so called costly, but given the above logic (250,000 miles to 1,000,000 miles) CHEAP CHEAP CHEAP??!! (200-300). In addition the oems can get the cost down exponentially LOWER if the oems put it in. (pure volume comes to mind here) Here you can in effect use a very "fine screen" filter. Indeed some Amsoil (EA models) bypass oil filters, literally microscopically scrub the oil to a cleaner conditions than when it comes factory sealed from the BOTTLE!!! Again Oxymoronically installation of this "benefit" can actually VOID or make tougher engine warranty fulfillment in the absolutely remote chance you do have engine issues. So statistics are really on your side when you follow what the OEM's recommend. When you want to do either slightly to radically different things, a little research and sites like www.bobistheoilguy.com come in handy and are indeed considered required. Again you will probably want to comply with oem recommendations during the relatively short warranty periods. After that, you self warranty anyway.

Replying to: rhouser2 (Nov 01, 2007 5:20 pm) As you can probably see and surmise, there are a lot more things going on than just changing your oil and filter at 3,000 miles. |
