Hi there all

took the car out for a spin today to see what was going on and if all working ok,

its a turbo charged bec

what i would like to know is does anyone know what oil temp it should ideally be running at normal temp,

it did creap up to around 96 deg after giving it some beans is this normal or to high i am not sure??

thanks for any input,

ps it is running a oil cooler

Sounds about right.

As long as oil remains below 120C you won't be doing any damage. In fact, for max power you want the oil around 100-110C (racers have been known to block off part of their cooling to get the oil upto this type of temp).

Make sure you use a good quality synthetic (don't believe the nutsack about synthetics being bad for clutches) and you'll be fine.

Yep, many bike engines are designed to run optimally at around 95 deg. I think these days that is the norm for sports bike engines. As progers says over 100C is not unusual when giving it some. Of course racers accept 20K mile rebuilds as part of life

As for the synthetic vs semi synthetic. Its not clutches that are a problem (use proper bike engine oil and its not an issue). Stick car oil in though and you pretty much will get clutch problems.

What you can find with fully synth versus semi synth is increased bore wear & oil consuption when you get the wrong type of the two for your engine. I've seem comments on here about people blowing oil seals using fully synth on semi synth engines too due to increased oil pressure. In the end the best way to protect the engine is the correct oil type and more frequent changes. A few bikers I know do an oil change only service half way between each normal services.

I think for car engines its something like 85 to 90

I thought Andy Bates often recommended a good semi-synth (Castrol GPS) for RGB use as its not quite as runny as fully synth so less likely to have surge issues.

I could be talking arse but when I ran fully synth and did an oil change I was concerned that it poured out like water...

the only prob with using fully synthetic oil is in older bike engines designed for semi synthetic, on some of them it can cause the clutch to slip. I've had this on a couple of bikes but not for a few years as designs move on. My zx7r was a pig for it.
