|Oil (again) - THe Growler|
Prowling round the car supermarket where I live and looking at motor oil yesterday, I note the following (I have made the sterling conversion at today's rate for the sake of clarity).
On the shelves Mobil 1 sells for £4.52/liter. Pennzoil, Quaker State, Valvoline, Caltex Havoline, Shell and Castrol brand synthetics sell for (+/-within a narrow range) £2.76/liter. From my local gas station Petron (that's the Philippine national oil company 40% owned by Saudi Aramco) synthetic sells for £2.58/liter. (For the sake of comparison, Caltex fossil 15w/40 sells for £1.41/liter). All rated API SL by the way.
Question: why is Mobil 1 more expensive for apparently a similar product and why would I buy it when there is a wide choice of cheaper and apparently identical synthetic oil alternatives in terms of specification?
Next question: what is the point of semi-synthetic oil? It appears to be something and nothing. My Harley Service Manual demands semi-synth in its transmission yet I have run it on Pennzoil 80w/90 fossil prior to changing to HD's own semi-synth a few months back and noticed no difference whatsoever (i.e. engaging first from neutral still frightens small dogs and old ladies hehe).
I await enlightenment.
