How often do you change oil on 172 Cup?

[nightSpirit]

I had the car serviced around 4-5 months ago and have covered 5k miles. I'm off to the Ring on Friday next week and contemplating a quick oil and filter swap before I go to keep things in shape...any thoughts?

 

[Ol’ Tarby]

I would. Then again when you come back. Although tbh I used to change the oil in mine whenever I got bored, gave me somethin to do lol

 

[Dave Hester]

On mine every 4 months

Filter £6 from local motor factors
Oil 10w/40w semi synth 5 litre £16 from asda

Approx 1 hour job, i can usually undo the filter by hand if im wearing my wifes marigolds for ultimate grip strength

[skiptontweed]

marigolds are perfect for that extra bit of grip.......

 

[Jimbo_M]

Between every 5-6 months i would say

 

[v16daf]

Every 6000 miles

 

[Spee]

Every 3 months or so, new OE filters, flush with cheap oil, allow to drain, fill with synthetic. Doesn't have to be top notch when you're changing this often either, my oil always comes out looking pretty healthy.

10/40 in a 172? Bit thick isn't it? Thought it was 5/40 fully synth?

i used to agree with this but with experiance on the f4r i would say change every 6 months but with decentish oil

using stuff like carlube etc encourages a noisy depahser in my experiance

 

[jenic]

Genuine filter and Fuchs Titan supersyn 5w40 every 6 months in mine.

 

[Nick172Cup]

Change mine either every 6 months/6k miles/5 trackdays. Just plain and simple Halfords 5w/40 full synthetic oil also as I get it cheap on trade!

This seems a bit extreme to be brutally honest, it is only a Clio not a supercar!

I love my car!

Simples.

exaclty the same thickness when hot - ie the 40

just thicker when cold

Aha! Cheers Fred. I know a little about oil, i.e viscosity and temp, but didn't realise they were the same at 40.

 

[Fred@BTM]

first number is the viscosity at 0degC, the lower the number the thinner it is, so a 0w is thinner than a 5W - so if you live in northern sweden you'd run a 0W40 (may a 0W30 if its REALLY cold)

second number is viscosity at 100degC 40 is the same as a 40 a 50 is thicker, 30 is thinner - if you lived in africa you'd run a 10W60

get it?

 

[Gaz_]

As per service schedule. Be reet. Genuine filter, elf oil, done.

 

[Fred@BTM]

^no, every 6K

why do you think dephasers rattle their **** off?

 

[Gaz_]

never had a rattling dephaser yet

Also I don't tend to keep cars on uber mileage either

 

[Fred@BTM]

money bags eh? :clown:

Flol I wish!

Yep!

 

[jenic]

I would insert a typical halfords joke but am still trying to work out why you need it thicker in warmer countries

If oil is too thin it doesn't work. Simples

 

[jenic]

But if the hotter it gets, the thicker it gets, then surely in our colder countries you need to be using 10w60 and over there a 5w40. Or does it go thinner after 100degC?

Other way mate. Hotter = thinner

 

[jenic]

Other way mate. Hotter = thinner

That makes sense chemistry wise to me.

But how come at 0degC it is 5 then at 100degC it is at 40 and a lower number is thinner so the thickness increases with heat, from 0 - 100degC at least. Or am I understanding this all wrong?

 

[nightSpirit]

bloody hell!

Done the job today, halfords 5x40 synth and filter...sorted. AP Racing brake fluid on its way and as I was bored, I've stripped the back out to save some weight, removed the fog lights to feed air to the filter and mount my bullet cam and tomorrow I might see if either my Profi 3 or Willans harnesses will go in.

Cheers for all the help!

Ah, see what you're getting at now. The higher viscosity, the thicker the oil is. The low/high numbers are independent readings because there is no heat initially, so the viscosity measurements don't correlate. Imagine it as two different tests.
The lower the number, the higher the viscosity at the given temperature set point.

 

[jenic]

Right, that makes sense now
