Mines a 1999 plate and its now on 54,000 with me having put 26,000 of those mines in about a year and 6 months.

Has anyone ever shot a Suzuki engine to test this hypothesis? :)

Yeah but no but....

If synth oil can mean longer service intervals then you save money on servicing.
If synth oil means less wear from cold then thats a good thing, benefits include less oil consumption (money saved), plus engine keeps its efficiency therefore uses less "expensive" petrol (lots of money saved).

So although I totally agree that most engines will outlive their owners Sid ;) an engine running sweet at 50k is better than a noisey, poor starting one which is 10mpg down on what it should be!

Just think if you commute 20 miles a day, 100 miles a week, 5k a year and your bike loses only 5mpg due to wear (this is proven by people saying they top up their oil between services), then over that year you are throwing away:

5000 miles - 5% = 250 miles

50mpg seems a general average consumption for most commuting SV riders so,

5 uk gallons at 94.9 per litre = £21.54
...and thats only a 5% difference...
This equates to a difference of only 2.5mpg at 50mpg so you would be getting 47.5mpg instead of 50mpg on the old worn engine.

My argument is....what is the point in throwing that £21 away every year.
The extra money spent on buying synthetic is cancelled by having longer service intervals. Don't worry, I've thought long and hard about this and it seems to make a lot of sense to me! ;)

Just paying more money for synthetic then changing it every 3k is daft because it has been proven to last much longer. You are throwing away perfectly good oil. Good for oil company....bad for consumer!

My last engine lasted 19k before the gearbox expired. See what happens with the second hand replacement. Engine swaps are easy when you have done them a few times, I found using some straps was a great way to get the engine out/in if your on own doing the swap.

I'm not sure if you guys across the pond use the same standards as we here in the U.S. but usually most motorcycle oil is sg rated and contains zinc. as with synthetics they may have better resiliance with heat, but You still have to replace it every 3000 miles synthetic or not.

Re: durability on the sv 650 motor
 

Around every 4000 miles here.

Mine changes itself every 4k anyway.

Have you got one of the rare special edition two stroke SV650's as well?
