As long as an engine is stored in a non-condensing environment I think the time frame constraints they put on oil changing is a nonsense. What's gonna happen to oil sat in a stationary gearbox that isnt gonna happen to it in the can in the shop? Granted condensation can cause moisture to emulsify the oil but in both cases it's in a in a sealed chamber with a limited amout of available moisture. Even with the engine oil, though the crank case is vented to atmosphere (or at least often the intake manifold) there is a very limited exchange of air going on when the motor isnt running. That oil which is already millions of years old isnt gonna age much more in another year is it?

Have a read of your manual SDDave... how do you interpret the oil & filter intervals. You could read it as oil and filter year one, just oil but leave the filter year two then oil and filter year 3 and so on.

That is certainly true where you were running it on an hours basis... oil every 100 and filter every 200.

I read it as oil every 100 hrs or 12 months whichever first, then Filter Every 12 months too unless you do 200 hrs within the first 12 months in which case change it at 200 hrs with the second oil change. It isnt the clearest is it!

Cheers

No it's not totally cleart.

Have a look at 3yrs or 36mths... no oil filter required which surely fits in with every other year??

I think you're looking at it as if column 2 is at 1 year old, column 3 is at 2 years old and column 4 at 3 years old, but it isn't. If that was the case hen there's no more servicing after 3 years old. Instead it is every 12, 24 or 36 months unless you hit the number of hours in that column sooner, so year 3 and year 6 service is the same unless you do 300 hrs a year in which case you will do that every year instead of every 3. Clear as mud eh!


Essentially it is making sure you change the oil according to the amount of hours it has protected the running engine for, unless you don't do many hours in which case they say you need to change it coz it's got old. That takes me back to my argument about whether another year on something that's already millions of years old is gonna make much difference. I have a mint 1989 ford Sierra XR4x4 2.9 V6 that I've had from new. It does about 600 miles a year and I change the oil about every 3 years whether it needs it or not: -) still running sweet as a nut. Roll on the warranty expiration so that common sense can kick in.

Well yes... and no... and that is why indeed it is clear as mud.

If it is as you read it why at 300hrs or 36mths would it show the oil filter isn't changed??

Also re it stopping at 3yrs they have detailed up to the greatest interval and expect you to know it is repeated thereafter??

I'm going to the muddy horses mouth tomorrow to find out for certain... Suzuki GB not my dealer as I want to be totally sure. I'll do it by mail so I have a recorded reply.

And if you want to know just how muddy the waters the workshop manual gives the schedules in a different way compared to the handbook... showing just the extra items for the 200hrs and 300hrs/36mths.

I see what you're saying, but in reality the only thing that needs to go in the 2 or 3 year interval columns are things that are not already in the 12 monthly one as they are each multiples of 12 months anyway and as such will be picked up by that. Maybe. That's the way I read now anyhow it but please do tell what the Oracle has to say about it. All good fun.


Bck to the diagnostics tool I had a thought. If it only works on the DF20 when the engine is running, what do you do if your fault prevents in from starting in the first place. OK many modern engines have limp modes etc that may allow it to start so that the ecu gets power to be interrogated, but what if it is a really fundamental failure that kills it flat. I guess in that case with a service manual and a multimeter you need to go back to old school methods. At the end of the day the dealer would be faced with the same problem other than the fact he may be able to exchange parts easier (and certainly cheaper) than we can.

Suzuki DF20AES - prop size

Ooer Guys. I've got service schedule brain ache now, time you guys got out on the water. 😄
Not got my service schedule in front of me now but I'm working on the 12 month/100hr items get done every year plus in year 2, 4, 6 etc. the 200hr items are added, and in year 3, 6, 9 etc the 300hr items are added, and timing belt (ouch) every four years.
As a leisure user, with low (approx. 40 hrs/yr) servicing will be based on time.
Working on the premise it's been serviced per schedule at an approved Suzuki service centre so the warranty will be intact. Not really expecting any problems though, engine runs like a dream.
