Astonished!

1st April 2007, 00:22

Basically a few days ago i noticed that my car wasn't realy pulling aswell as it used to in 3rd and 4th, nothing too bad but you could just tell it wasn't quite right. My car was also due a service and i had serviced it 10k ago (roughly). So went and got an air filter, castrol 0w-40 fully synthetic oil and and oil filter, did the service and now its loads better, i am very surprised at the difference tbh! Abyone else ever had this?
Cheers.

Yep a good service can do wonders

1st April 2007, 01:36

and did you replace the sump plug washer ???

1st April 2007, 09:04

i service mine every 6k to 7k and never really have any problems with loss of power, every now and again i get a flat spot of a day or so but thats it.

i serviced my mates vtr that hadnt been done in about 15,000 miles and it runs alot better now so yes it does make a big difference

A little advice on your choice of oil there pal. It's not perfect for you car IMO. It's fully synthetic which is good thing (if your engine is low mileage that is!) but it's quite a thin oil. You'll probably notice a little more noise from the engine bay. I personally would NOT put that oil in my 106, and my mileage is less than 40K!

I agree. When I put 0w40 fully synthetic in mine, my plugs kept oiling up because the oil was very thin and getting past the piston rings.

I stick with 10w40 Semi or fully.

1st April 2007, 10:43

Nice one ColSax, that's a good point!

Some further comments... If you want performance, go for 5W40 full/syn. But not if you'r car is a high mileage one. Best put 10W40 in that case, just as ColSax has said.

1st April 2007, 10:55

ill have to make sure i keep my sax good on service

1st April 2007, 11:10

Predater: yeah i did, lol.

also about the oil i put a post up and oilman said it was a good oil to use..

1st April 2007, 11:19

Invite him to argue his case then. I'm no expert, but what we've said is pretty much bread and butter really. If there are some less obvious reasons / special properties of this Castrol oil, I'll be interested to know.

1st April 2007, 11:45

Weel its thinner so it gets to places that other oils cant therefore providing better lubrication and its fully synthetic which offers better protection than semi synthetic..

1st April 2007, 11:49

All for the wrong reasons I'm afraid. The 5W40 will get to ALL the places that it needs to. The protection will be less, as it's thinner.

1st April 2007, 11:56

Well when i had an rs 125 2 stroke it was always said that you should use fully synthetic oil to protect the engine as well as possible..

I aint arguing about fucking oil, its in my engine not yours so dont worry, but as for saying fully synthetic oil doesn't protect and engine very well, says it all IMO

1st April 2007, 13:02

You're an idiot, that says it all in my opinion. Run oil too thin for your engine, and you will be taking risks of wearing out parts, and pretty much shortening the lifespan of your engine. Fully synthetic does not just mean protection, FFS!

1st April 2007, 13:03

hi
i fitted a k&n filter last summer and its coming round to service time again.

would you recommend totally replacing it or is it ok to use that K&n filter cleaner?

cheers

1st April 2007, 13:04

sorry wrong forum oopss!!

Well tbh mate iam going by what an experienced oil specialist has told me and you cant blame me for that. Also how is it too thin?? According to the citroen manual 0w-40 is fine. As for shortening the lifespan, well i disagree totally, as the oil is thinner its getting to places where semi syn and mineral oil cant get too. Also castrol's high mileage oil is thinner still than what i'm using so explain that one away..

Just thought i would throw that in too..

There's another one for you..

How about another one..

1st April 2007, 13:17

You're now even more of an idiot than I first thought.

1st April 2007, 13:19

Alright mate, you sound an expert so can you explain to me why all those quotes are wrong.

1st April 2007, 13:31

You need to understanding the information you're ranting off about. Firstly, a thinner oil means less protection. (generally speaking) Just because it's fully synthetic doesn't mean you can just forget about the grade. Why do you think there are such things as recommended engine oil grades for different engines? Thinking that you can get better protection with thinner oil than what's recommended for your engine, just because the oil is going to better areas of the engine is just crazy. I'm sure a test was published once, where they showed some differences between synthetic oil Vs semi synthetic. The synthetic oil has a tendancy to move towards heat, whereas the other oil type doesn't quite so much. Fully synthetic oil is a good thing, I'm not aruguing that! But if you want performance you will pay the price of protection, you can not have your cake and eat it!

The grade i use is in the citroen manual and its recommended that fully syn or semi is used so i'm following those guidlines.. where your getting the fact that i'm out of those guidlines i dont know. Also the oil i'm using is fine as i have showed you in those quotes from an experienced oil specialist..

1st April 2007, 13:49

If your manual recommends 0W40 then that's spot on. ...But are you sure on that? I would have thought 10W40. Anyway, as engines get older, it's a good idea to use a thicker oil. I would only use a slightly thinner oil than recommended when the engine is still young. I'm using Silkolene's 5W40 fully synthetic. But I can't use it forever, I will move up to a 10W40 at some point in time.

1st April 2007, 13:58

Yeah i'm postive, its on a little graph thing..

1st April 2007, 14:54

Calm it please! lol

I just wrote down on here my experiences thats all.

I use castor oil pre-mix in 2 strokes BTW. But Castrol TTS in my RGV 250. Chainsaw oil works well too.

Thin oils tend to sweep away all the oil keeping the oil seals in place too, again thats what I found.

Thin oils are normally used in high revving motors i thought.

1st April 2007, 14:57

lol, i wasnt having a go mate. sorry if you thought i was..

1st April 2007, 15:01

I dont mind. Life is about experiences and experiments. And owning a Saxo use both them theorys.

1st April 2007, 17:02

using thin oil eg 0w-40 will damage a high mileage engine. i dont think citroen recommend usin 0w oils anyway??

a thin oil will only get alot thinner when it becomes hot, altho its fully synthetic, it will still not protect as much as a 5w fully synthetic oil when running hot.

if you are ragging your car around on 0w oil and its hot, it will work its way into places that may have build ups and losen them eg from the bottom of the sump, this will also lead to problems.

try and always stick to the same kind of oil and you shouldnt see many problems.

i always go for 5w-40 or 10w-40 fully synthetic

castrol rs

but like you said, its your engine. i dont want to be roped into any arguments either

lol just trying to help out

1st April 2007, 20:16

Where do you guys put the left over oil afterwards? I need to service mine but haven't got a clue what to do with the old oil

If its a little sneaky, pm me please

1st April 2007, 23:20

LMAO. Nothing sneaky at all. There's plenty of places where you can just get ridof it. Usually into a big vat. You'll find this at certain recycling areas.

No no thats fair enough mate.. I was just going by info that i have been told by this oilman chap.

If you look in the owners manual there is a little graph, 0w-40 is on there..

2nd April 2007, 00:00

ok mate, never looked in the manual hence the questions marks after what i posted

2nd April 2007, 00:13

Yeah thats ok chap!

2nd April 2007, 00:23

Well we run a very highly tuned TU motor in the car, and we run Mobil 1 fully synth 0W-40 and after a years worth of events, have had no problems with the oil.

The car is regularly revved to the limiter on the straights @ 8400 ish, but the oil is changed probably more regularly than most people on here do. It gets changed every 150ish competitive miles and 400ish road.

2nd April 2007, 00:31

Yeah i thought you might run an oil like that in the rally car, if you want to protect an engine under alot of stress and high temps then fully syn is the way to go and thinner it is the better i think as it will get to places where other thicker oils wont. Just my opinion based on things i have read and heard.

I'm also using this oil as recommended by mr oilman changing it around every 5k miles, my cars past 100k and runs like new no signs of wear.

2nd April 2007, 09:30

same here mate, 105k mines on and there is no smoke when driing hard etc and pulls really well still too.
