Autolube

How many litres of petrol do you reckon to use before you oil tank needs a refill? (2 stroke obviously)

Most times I top mine up every time I refuel, but last weekend, (anglesey cruise), I refilled fuel at sea and left the oil alone. Checking it when I got home it was low low. So I reckon approx 100 litres fuel and it would be empty.

I wondered if this was about right and the same for others?

You have not said how much oil is in the tank?
I would have thought 100 to 1 ratio so 1tl of oil?

It's worth carrying a litre in the console for emergencies.

Has it got an alarm for when it hits a level, or does it run dry?

[benjytaylor]

A 40hp yammie has a 1.5lt oil tank. The 75-90 autolube has 3.3ltr oil tank.

[IndyR1]

My 60hp uses little oil and I'd have needed to mark the tank in order that I had known how much was used on the Anglesey day as it would have not dropped that much.

I guess unless I really do a lot of miles I'll probably only fill up my tank once more in a season.

My yam used to use hardly any, say a tank 1.5l to every 90 to 100 l of petrol. The opti has used about that on 50 litres ish.

Il check the size of the oil tank. Not sue about an alarm it's a 2001 merc 90. I can probably find the spec on t'internet

Just felt like a lot of oil being used but maybe not

Should have, couple of blue wires (i think) leading under the tank.

Hi ,
My Yamaha 90 was my first 2 stroke engine and I was shocked about the high oil consumption . I had a few times a fuel / oil burn ratio of 1 : 45 !!
I asked a Yamaha dealer on the IOM and he replied the following :

"Hi, Jurgen, all modern pre-mix (manually mixed fuel) Yamaha’s are specified at 100:1, but at 50:1 ratio for Autolube engines, so your 45:1 is quite normal and within tolerance.
"

Regards - Jürgen

Etecs on the "ordinary" TCW3 setting average about 50:1, on the XD100 setting they average around 75:1. Modern autolubes will vary the oil ratio depending on running conditions. At tickover, oil consumption will be negligible, hard acceleration dramatically increases oil useage. If you are continually on & off the throttle (rough seas?) oil use will be higher compared to a steady cruising speed.

Cheers Dave that makes a lot of sense. It was as rough as toast Anglesey weekend. Engine runs fine so I'll not tamper with it . All good thanks Neil
