Fully synthetic oils

[Scottie]

Bit of triva I picked up been on a course the last few days on
Lubricants and as I'm sure you all know Castrol Duckhams etc etc is all BP anyway good bit of advice for any new car owners during run in period.


"You should not be flooring ( like any of us would be tempted) the car when it hasn’t been ran in correctly, you could glaze the cylinders, which means that your going to burn more oil. Also glazing can lengthen the running in period and lower your fuel consumption. Glazing is a by-product of the latest fully synthetic oils, although the oils are the best yet, they have this side affect, where being too gentle or to harsh on the motor in the initial 2000 miles doesn’t do the cylinder linings much good.

The smoke could be exacerbated by this phenomenon and more oil used.

They say and I'm only quoting that a engine that uses fully synthectic oil is only fully bedded after 5000k.

Just drain the fully synth stuff out of the car and put halfrauds 20w/50 in and boot it too yer hearts content. Then drain it after 5k and go back to the full synth again, After flushing the system first though

Yup - spoke to an oil specialist when I had my coop and he recommended draining the oil at 1000 miles and putting in semi-synthetic for the next 5000 then flushing the sytem and reverting back to fully synthetic to assist the running in process and avoid glazing.

Needless to say that never happened!! :I

Hey Col, did your car ever stop guzzling the oil then?

[Gismo]

It's all relative of course, apart from the warranty being voided if discovered :p hardly any one ever keeps their car long enough to glaze the cylinders anyway ;)

It's still burning a little oil BD but nowhere near as much. :)
