Has anyone ever; for their oil/filter change cycles maintained an every 3k for the filter interval but went 6k and up on the oil drain interval? I am referring to use of synthetics just to be clear. For example: 3k miles: oil change w/filter 6k miles: just oil filter and top off oil level 9k miles: oil change w/filter 12k miles: just oil filter and top off oil level and so on. and so on.
Just change them both, unless your car is 100% stock I wouldn't suggest going over 4k. But I'm sure other people wait longer.
I dont care what anyone says, subarus are picky as hell about oil quality and levels, change oil and filter 4.5k maximum, syn or not, if the car is a brand new car, good luck getting any kind of warranty coverage with those intervals.
Oil isn't somewhere I want to be cutting corners on a $30k+ car. It's cheap insurance to just do the "whole thing" every time, warranty bs not even considered...
Same here, but my old Saturn had so much blow-by I was doing it every 2500 mi/3 mo with dino not synthetic, although with the scooby I am using synthetic As far as the op goes I was just curious if any one has heard of, seen or done this other than me. I had a co-worker at my last shop I worked at did this to all of his and his families vehicles with magic 1. I have always thought it an interesting concept if anyone is running extended mileages. If you think about the fact that synthetics are designed to be run to x,xxx to xx,xxx mile claims that the oil can handle. An issue with that is that of the life of the oil filter, if the filter cannot "clean" the oil, it would cause wear on the internals, but in replacing the filter it would be theoretically like starting a new with the addition of fresh top off oil. Therefore, one should be able to do it with less worry than going to x,xxx- xx,xxx mileage on just one filter. If i had a NA domestic that didn't have a ton of blow-by like my last car, I would be willing try this and send out the oil for analysis.
Or you could just change your damn oil and filter every 3000-4000 miles and not risk ****ting your engine out. No oil is designed to be run to X mileage. It's a suggested mileage. Oil wears out. It just does. In an N/A car your oil isn't subjected to nearly the same abuse as it is in a turbocharged motor. So, while your oil might say 5000 miles, that's 5000 miles of commuter driving in an N/A car. Here's a question, if you put Mobil DriveClean 10,000 in a Forumula 1 car and go racing, will you be able to race for the entire season on one oil change? It's your motor. You'll do with it as you like. But oil's ability to lubricate parts is not 100% dependent upon the amount of dissolved solids that are collected and filtered. And if you are thinking about trying this little experiment with Mobil 1, you are in for a rude surprise. As M1 turns to the consistency of warm piss after about 1500-2000 miles. No amount of filtering is going to fix that.
lol, and i do my oil/filter at 3k-4k. Thanks for the clear up, sorry i used the wrong description/info. Your right the oil does break down, but synthetics break down at a slower rate than that of dinos hence the higher suggested mileages than that of dino, unless there is a problem with the engine, like blow-by that sludges the oil. mmm, didn't i say i'd be willing to try it in a NA motor? I did mean as a dd commuter. I realize that forced induction is a different environment from NA and I am not saying that anyone should try this let alone in anything that revs higher than 8k. As far as the f1 question goes if you had that kind of disposable income, this would not even be considered would it? Are not well backed race teams routinely inspecting/ tearing down and rebuilding the engines, therefore that would mean they would have to put the drained oil back into the engine. but the question was to provide a good point, of course one would not wanna do this little experiment on anything but a NA dd that is totally stock, if one was willing to risk of damage to their motor. I was merely just surprised by the notion of the idea. I did not come up with this however, the two main vehicles that my former co worker put the most miles on are both over 150k, a Cavalier and a Tahoe that he tows with(a GM nut). I am not sure if he did this from the 1st oil changes. +1 agreed on sentiments toward Mobil, its utter crap. Back to the OP, I was just curious to see if anyone else has heard of doing this and gauging from the flak i'd say no, Although if one does run their oil to the X suggested mileage, why not swap the filter out once in the middle of interval? it cant do too much more damage than not swapping it out. Readymix, and everyone thank you for the input, it truly is welcomed as this was an inquiry as to see what people thought about this, maybe i should've found a commuter forum, not mnsub.
Yeah... we tend to be a little defensive over our engine internals. We blow enough engines as it is without oil tomfoolery.
The reason I am heated about it is that for the half dozen or so people that come in here that are extremely against it, you have about the same amount of people on here that don't have a clue about oil that go "hmmm, that seems reasonable, I'm gonna try it. He's getting alot of flak for his opinion, so I'm going to secretly prove all of those jerks wrong" and then they crap their engines out. And this isn't some dumb hypothetical, it happens. It's the reason that stupid HHO fad got so big. It's because stubborn retards have to prove people wrong, even in the face of facts. And while I agree that an NA daily driver car that you commute highway miles on every day can probably get by just fine with longer oil change intervals, especially with a clean filter, some bonehead on here will read it as "I can run my STi on Mobil1 Jesus Oil for 10000 miles because it's a synthetic as long as I change my filter at 5000 miles, herpaderp." The terms have to be spelled out, as well as the dangers, otherwise you are going to have a lynch mob after you for suggesting things like this because a bunch of idiots can't read between the lines. And yes, that's a pretty dark observation, but it's reality.
Thanks readymix for being the one to step up and help out with this. It means a lot and maybe i should have been more crystal clear in the op, but its reassuring to see that you are here to spell out the warnings and dish out the point out that this would be a bone headed move in most if not all applications. Considering we are a severe service state not normal service for vehicle operation. Hell our winters prove that for us, but they sure can be fun.
Looking at my motorcyle (07 GSX-R600) factory maintenance schedule it looks like the one originally posted. for oil and filter it shows Oil/filter at 600 miles-oil at 4,000-oil at 7500-oil/filter at 11,000-oil at 14,500 18,00 etc...Of coure I'm doing the filter with every change and doing it more often but still find it curious that such a high reving (high?) compression 12.5-1 motor would have these type of intervals from the factory. May be apples to oranges comparing bikes and cars but I knew this sorta interval thingy sounded familiar when I read it.
The real question though are you recommended by manufacturer to run syn or dino in the GSX-R? That was kind of a shock to read.
Well, it all comes down to how your motor treats your oil and the only way to tell that is to send in samples for oil analysis. I do 8-9k for a oil change and filter on the fxt and the lgt. Amsoil said that I can probably go another 6-7k on it. But if you plan on just changing the oil every 3k, I sure as hell would not be buying any kind of expensive synth oils. Russ
Not sure? It just says they recommend SUZUKI PERFORMANCE 4 MOTOR OIL or equivalent. Use of SF/SG or SH/SJ in API with MA in JASO. It looks like the have both dino and "racing" versions of their oil.
Each car is different, and oil wear depends a ton on how you drive (always less than 5-10 miles, or 50 miles to/from work, etc). If you really want some hard numbers, I'd suggest sending a used sample to Blackstone Labs. They'll give you some particulars and suggest an oil change interval based on the oil quality and numbers you send them.
I might be opening up a can of worms here, but do they teach "how to be completely obvlivious to the well-being of my car" in driver's ed these days? I dont know how many times this year I've had to listen to cars in the shop knocking like crazy with little to no oil in them, "my car has the cracked pickup tube problem" No, it doesnt, it has no freaking oil in it! CHECK YOUR OIL! 3 of the 4 motor jobs in the shop right now are because of lack of oil changes (6K dino oil intervals) and never checking the level.
+1 for this, my co-worker thinks it was ok that he didn't change his oil for 20-30k (he claims) but yet his car has a bunch of issues. This is also the same guy that says "higher octane gas is just so they can charge you more."
Wow, I think the highest I have seen while slinging oil at work has been 18k and 2 years on the sticker with dino, it had some nasty valve noise, the owner shrugged it off and said "Oh, I just need an oil change." he was back for a engine 3 or 4 weeks later no start and got a used engine from a junk yard. the car only had about 80k on it...
