5w50 any problems?

[JDC5]

Hi all

Just wondering if anyone is running 5w50 oil?

It's just that I've always put in Pro S 5w40 but I seem to b topping up at te end of every week.

My car is supercharged so i know it gets very hot under the bonnet, so would I run into in problems if I did use 5w50 oil instead of 5w40?

Is 5w50 recommended for a charged engine?

Cheers

10w60 is recommended for forced induction due to the higher temps

Personally I would use castrol edge sport 10w60 ( it's for the BMW M series engines now) as I always have done in all our Hondas , it uses very little and works well daily or racing

Thanks guys. I will be ordering some 10w60 oil now. I cant seem to find any 5w60?

in the mean time can i mix in some semi-synthetic oil for a top up as im running very low just until the thicker oil comes?

cheers

Yep shouldn't be a problem but id advise taking it easy until you get the new oil in there just to be super safe

Thanks all for the advice

Just ordered two 4l of Castrol Edge @ £28 each! Bargain!!

Hopefully with this oil I wouldn't need to top up as much compared to 5w40

where has this come from? im not taking a dig, just asking

I've been using 10w60 and its much better then the 5w40 Pro S, I notice that the oil is still a goldie colour after a few thousand miles whereas the Pro S stuff turned rather black. Also i havent topped up since and i know with the 5w40 i would have topped up a few times by now.

So i can see for my own eyes now that 10w60 is right for force induction indeed!

I'm not a scientist so this might not be 100% accurate but the theory goes like this.

Forced induction engines run hotter for a number of reasons (I'll assume you know this), so therefore you need a slightly thicker oil to achieve the same lubrication results that you would achieve on an N/A engine with thinner oil.

Saying that I used to run 10w60 on my car when it was N/A also

JDC5 - Yep noticeable difference in topup intervals with the 60 weight

would 10w60 be ok on stock, but for trackday purpose? (high revving) = more temp. or that's too heavy?

I'd say recommended tbh rather than "ok"

TGM run it for all their race cars
