What engine oil?

[ts2]

i don't believe that to be the case.

Don't worry, I don't totally believe it myself, I was hoping someone would tell me why it'd run hotter in summer, as as far as I know an explosion is an explosion, so the temperature would be the same. The difference is the air temp going in and the air temp cooling the engine? Maybe there's more?

the ambient temp will affect the temperature of the engine to some extent, especially on an air cooled engine.

If you spend enough time stuck in stop-start traffic, commuting in very warm conditions, with poor air flow through the oil cooler, the oil can get hot enough for the viscosity to fall below the pump-pressure threshold. The motor would sound clattery. Hard to miss. If this happens, a heavier oil could stay in grade at the higher temps, or you could stop playing in the traffic.

If that's not happening, you are good to go. For what it's worth, where I ride the summer temps are 32 to 42*C, but I don't do heavy traffic. And I use Delvac 1, a 5W40 fleet oil.

If there is an explosion in your engine, is not running or set up correctly, you should have a controlled burn.....................my knowledge ends

Additive

the manual has been updated and the Castrol site will be soon to reverse the recommendations to >>20/50 as first choice

BTW 1150 and 1200 same oil

I do use Castrol in mine, however I use with Metabond oil additive. It gives more power and reduce the friction. www.metabond.co

And of course you have no connection to this company.
It's purely a coincidence that your first post is on a 5 year old thread and it just happens to be plugging a product.
By the way.........all oil additives are a load of shite, along the lines of copper bangles.

Good points even if they're from 2009 ... and judging by where you are and the summer temps.... I reckon 10/40 would be absolutely fine in the UK .... can't remember the last time it was 42c here

Ah - but not all copper bangles are created equal. If made with Reassuringly Expensive oxygen-free copper (just like the stuff they use in high-end Hi-Fi leads) they can have real benefits. Admittedly, these benefits work almost entirely in the favour of the people selling them, but they are benefits all the same!

Last year how many days went above 30c, and how many below -10c? in the UK?

10 successive days with temp -12 on Exmoor!

No running water in house or stables, leat and river froze solid but GSA started on Halfords economy 20/50 so we could go to the swimming baths in Tiverton to wash

Believe that and you'll believe anything.

Who with a 1200GS in this thread is likely to keep it for more than 20K miles before changing/part exchanging it for the latest newest model when the current warranty runs out.

I am that man, Neil.

 

[Roymondo]

Me too - 27k miles and now 12 months out of warranty. Can't see myself buying another bike any time soon, TBH.
