Oil change based on Hours

Guys,

I installed one hour meter in my amphi and I was wondering how many hours interval will be ok to change the oil.

I did some calculations based in a regular car, mineral(changes oil every 7500kms). Let's say that this cars runs 100km/h constantly, so will change oil every 75hours. 75 hours will be a good number for the amphicar ?

Jaques,
US Owners Manual says, under average conditions, every 3000 Miles, or 30 hours in water.
US Maintenance Manual: Every 1600 Miles or 25 hours in water.
German Owners and Maintenance Manual: Every 2500 km or 25 hours in water.

It's time, not hours.



Change it once a year. If you have a problem with the carburettor flooding
then change it straight after that as the fuel gets into the oil pan and
dilutes the oil causing lots of problems.



Some people prefer synthetic oils, if you go that route then try not to go
too thin, it's the first number that is important. 15w would be OK but I
wouldn't use a 10w or lower. The base oil is too thin and the additives
don't work well in old engines. Synthetic 20w/50 can be found. I use
ordinary 20W/50. No particular brand, but make sure it is rated API/SE. Some
cheaper oil isn't.



You need 4.5 litres to fill up and note the difference between high and low
on the dipstick is exactly 1 litre.

I don't feel confortable using synthetic in old engines. I don't plan to use the
car during the winter, but if I need to start it to move from one side to
another side, or something else, I'll need to have at least 10W30 (winter here
goes from -10 to -35). 10W30 mineral will be too thin ?

I found one that says that is ideal for old/high mileage engines.

It will take 4,5 litres with filter change ?

I have used synthetics in my Amphi, a '68 Olds, a '74 Porsche 914, and many
others. Never a problem.

That should be fine if it's cold but you really want something with higher
numbers for normal weather.



It takes a little less than 4.5 litres on a normal change as it doesn't all
come out !

Most amphicars do not get many hours on them after the rush of using them wears a bit,, They should for sure be change once a year, in Cold country I like to do it in the fall before storage to get the dirt out before it settles to the bottom.
Oil; todays oil does not have the right mixes anymore for solid lifts and danger of camshaft wear can happen,Make sure you are not buying this type of oil.including oils made for high milage cars.
Type 30 or 40 Hd is getting very hard to find.
but Shell makes a oil for Diesel engines that still has this protection and is avail in 15w40.(good and thick)

Humm, good tip Gord. I use Syntetic 15W40 diesel oil on my Golf TDI, so I'll
start using the same one on the Amphi.

Tks for the nice reception and tour on your place ! My parents loved your cars.

I already installed the muffler and now my car sounds as it should.

Jacques
