Replying to: kiawah (Aug 04, 2009 3:38 pm) I think 5000 miles for synthetic is more fanatical than 3000 on conventional. I'm pretty sure you should go 2x to maintain a consistent level of fanaticism.   As a non fanatic, as long as we are not talking about cars with turbos or anything, I figure 5000 miles is good for conventional and 10K for synthetic.

10K sounds about right to me. I've always suspected that the bet is safer if you are using diester or polyol ester base synthetic.

Tend to agree with you on these mileage figures...synthetic is supposed to be so good that a longer interval time surly makes sense. My local mechanic has synthetic for $44.00 which sounds pretty good and he's encouraged me to do it. That would be a once a year change interval for me since I probably won't even hit 4.5k miles driven on my car this year. My spinal issues have made me cut back on almost all non essential driving so I do it mainly to get to work and see my doctor monthly. Other family members have been doing all the other driving chores for me, which is turning out to be a great thing. Just don't feel the love of driving anymore .   The Sandman

Replying to: kiawah (Aug 04, 2009 3:38 pm) I used to be that way. Every 2.5 - 3K. If it went over 3K I started going into shock until I could get it changed. But after doing hours of research and reading on these forums and other places, I have settled on a 10K M1 change for all my vehicles. Saves me a lot of time and money since that only occurs once a year 2 of my vehicles and every 9 months for another. I could probably go more, but 10K is a nice easy round number to remember and I've set so that it hits at numbers like 120K, 130K and so on...

I change my oil once a year. I have been doing this for over 20 years and have never had an engine problem. I drive about 20k per year. I always pull a sample of oil and send it to Oil Analyzers to see if it did need to be changed or if I'm having a problem with my engine. I use only Amsoil with an Amsoil oil filter. Why waste good oil if what your putting in is no better than what your draining out.

Aren't there two driving conditions covered by Owner's Manuals?: 1.) normal, ie. trips that are longer than just a short trips and relatively minimal stops - requiring longer OCI; 2:) severe -short trips with many stops, requiring OCI closer to the normal and traditional 3,000 miles/5,000 kms or three months - whichever comes first. Oil analysis for less than 14 quarts is not cost effective but can show information about the engine that would be useful for detecting deficiencies invisible any other way. The 7,500 - (6 months), 25,000 and even 35,000 (one year) options with the above mention brand shows what protection is offered but you still need to be sensible about the how long you go before an oil change/oil analysis.

Replying to: rhiebert (Aug 05, 2009 2:22 pm) Indeed, using good sense based on real research and experience should lead to a reasonable OCI for whatever petrolube or synlube you select. Several years back, petroleum oils got so inexpensive from sources like Checker that I went that way for all my vehicles. Of late, the game seems to be over, and the bang for the buck is back in the synthetic oil products, presuming you shop for price. An easy cost per mile analysis is all it takes to make a sound choice. Vehicles that require special lubes are a possible exception, of course.

It costs $6.75 for a quart of synthetic oil and $22.55 for the oil analysis. With a filter it costs me about $83 per year (with tax and freight) for an oil change and knowing everything is OK. You need to compare that to what that is costing you and what the wear is on your engine. It has always worked for me.

Replying to: rhiebert (Aug 05, 2009 2:22 pm) Aren't there two driving conditions covered by Owner's Manuals?   Yes, often there are. But, my wife's VW, which requires synthetic, has only one schedule listed...10,000 mi or 12 months.   severe -short trips with many stops, requiring OCI closer to the normal and traditional 3,000 miles/5,000 kms or three months - whichever comes first.   No, I don't think they are usually that extreme any more. For my 2007 Mazda that schedule is 5000 miles or 4 months...and that is with conventional, not synthetic oil.
