What ever mix you decide on make sure your measuring jug is accurate because most are not.

Oil from Auchan is a bolt on to the 250 bottles of wine.

Doesn't adding more oil make the mixture leaner because there's less fuel?a.j wrote:Oh, 3% semi synth around town, 4% on the motorway if riding to rallies.Chris in Margate wrote:6 litres of best available and a 1/4 inch short of 2 oil jugs (just under 200 mls. Approx 33:1
Semi synthetic from Auchan in France €9.50 for 2 litres. Less than £8.

Short answer is yes.
Changing up oil mix ratios ot types of oil is ASKING to burn up a top end.
At the end of the day pick an oil, pick a ratio and stick with it.
I run 32:1 (3%) Yamahalube R every time from the first kick, on all types of top ends and I haven't seized a motor or holed a piston in close to 20 years.

I am of the opinion that adding extra oil for a longer journey could well induce the engine to run weaker and hotter.
It depends on who you talk too.
I used 3% Putolene Scootx in my standard 150 on advice from a dealer.
AF recommend 4% in their cylinders.
A work mate runs a competition trial bike and has dropped his rato from 4% to 2% fully synthetic on he advice of a Bultaco tuning guru, who recons modern oils are significantly better than the oils around when the bike was designed.
I have gone for 4% fully synthetic on the premis, oil is cheaper than bearings, thats what the designers of my cylinder recommend and if I screw up when fuelling then there is better than 3% in the tank.

If you have 5 litres of petrol and add 2% oil mix then you have your 2% fuel oil mixture.
Adding more oil (say to 4%) to 5 litres of petrol surely does not make the mixture weaker, you still have 5 litres of petrol plus additional oil?

Spanner check the running gear before every outing, like in the Army. You know it makes sense!

Hmmmm.....No.
The ratio of oil to petrol has changed. When it mixes together there will be less petrol and more oil going into the carb/barrel....but the same amount of air......hence a leaner burn.............I think ?
