3k on syn seems a bit overkill to me. Now if it was a turboed engine then 3k would seem about right if you have a heavy right foot.
Maybe you missed the part that my oil change is about $12. A top end or bottom end rebuild for that matter can cost upwards of $2k.
You HAVE to change your oil at some time...so lets just say this... $12/oil change...
166.66 oil changes is an engine rebuild. Thats $2000
At lets say 3000 miles an oil change that is 499,980 miles...I know my truck won't make it to that...
So how is it costing more than a top end rebuild? I'm not understanding that part? I have 82k on my truck, I bought it with 36k, so I've drove 46k miles, at 3k mile intervals that is 15.33 oil changes. At $12 a pop...thats $184 dollars in oil changes.
Now lets just say that you don't get oil for cost...it's about 25 an oil change with filter. Now it would be $383.25 so far that I've spent in oil changes. If I were to stretch that out to the $2000 mark of a top end rebuild (that 2k is just a number to use, top end rebuilds in my area are costly, mechs. know they can rape you, so they usually do) I can get 80 oil changes for $2000. So that is 3k mile intervals, that is 240,000 miles of oil changes...I doubt my engine will make it to that either, but it's good to try!
Now lets go with the "saving money aspect". You say you change oil at 7.5k miles...I have drove 46k miles on my truck.
Thats 6.13 oil changes at $25 a pop. That is $153.25 in total oil changes if I did the 7500 mile oil change. I'm not even including the fact that the filter should be replaced halfway through...
So you would save aprox. $230. That is a little chunk of change...but enough to rebuild a topend? No, I don't think so.
Lets say you do 15k mile oil changes, you save $308.25. Now thats an even bigger chunk of change, but enough to rebuild your motor? Nope.
Now I'm even counting the fact that parts to rebuild the motor is about 400...but who's going to do it? The average joe can't! I can't, but I know friends who will do it for me, even then it's going to cost a little more for a bill or two for them and pizza and beer.
So the theory that these long oil changes saves you enough money to rebuild your topend, it's not true. You save a mere 300 dollars if you do 15k mile intervals, of course its more over time, but I'm just using my exact case for an example.
The reason my oil gets so dirty is that I tow. My truck is my tow truck for now, I tow 3k# about 2x a week.
So if you guys want to save $300, I guess you can change your oil when it's chocolate black and 15000 miles...but I'd rather spend the money. I honeslty think it's being cheap not changing your oil at 3k or even 5k miles, not to mention it's lazy, and most people admit it. I'm doing the cheapest maintenance I can, thats changing oil...not that hard. TAkes me 10mins max.
The cost of the oil, say even 500 so far, is CHEAP insurrance. Compared to 2k for a rebuild.
The big difference is that the inside of my motor, besides for carbon, is pretty decently clean. I had to have a few gaskets and seals replaced, and it's pretty darn clean...compared to another ranger that was in the shop with about the same miles...who did LONG oil change intervals.
And I can guarantee if I didn't keep up on my oil, I would have had to rebuild so far...my truck has seen a lot of crap. It's been sunk, mudd(ed), etc. I am hard on it...hence why I don't mind spending the money on the oil change.
Like I said, if you think I'm crazy with my truck, I change my oil on my 4 wheeler every/every other ride depending. I only put about 12-15hrs on it between oil changes. Thats about 50 miles...crazy, I know, but top ends on those are about 1200. That oil cost me 10 a change. Cheap insurrance, I play in the water, and mud. It's a toy.
