Morning guys hope everyone’s well, so as the titles suggests yay or nay? Have a tuned car so Intend doing oil services every 5k miles or year whatever comes sooner, just realised the other day I’m coming up to a year in about a months time and I’m a few hundred miles over the 5k mark now. Good idea or bad? Seeings as it’s lockdown and the weathers been nice I can do a few bits on the car. Seen a few YouTube vids and it seems only a 100ml or there abouts is left over once cracking the nut open from under the car, surely this isn’t a huge deal? Last service was done by dealer in may 2019 at 26k miles now on 31k ish....


Thanks

Can you change the filter without jacking up the car?

As above; which car have you got and where is the filter located? Access to that needs to be easy ideally...

I do my own changes on my E39 530i, filter is on top of the engine and easy access to the dipstick tube... So warm the engine & oil up for 10mins and away you go smile It's that simple

I use the following:

Oil catch can: https://www.amazon.co.uk/Sealey-DRP07-10ltr-Recycl...

I use an extractor for interim oil services, gets most of the oil out, I figure it's a lot better than no oil change!

Yeah my thought exactly, Surely I’d be doing more good then harm changing oil every 5k

If I could be certain that it would remove most of the oil and I could change the filter from the top then I would use one.

That’s the question.. if you’re jacking it up to spin off the filter I just drain the usual way. If like a lot of modern stuff you can do the filter from above then I use an extraction pump. I have found in the cars I’ve done it in that all of it comes out, certainly the same as if you dropped the sump plug and didn’t leave it for a while to let it fully stop dripping.

There is an argument to say that if you don’t get under the car you might miss other things whilst your poking around but if you’re passionate about your car then you probably know it very well anyway.

In short, I use one and it gets my vote.

Thanks mate, after watching a few vids on same car and same extractor as mine, seems a mere 100ml is left over, in my opinion that’s not too bad?

Not too bad really... I think they are 4.6L capacity on the TFSI/TSI so to get all out but 100ml is decent.

It’s a stage 2 golf R, with a stock car, manufacture suggests oil service every 10kmiles or year whatever comes sooner and a full service every 20kmiles or every 2 years, again whatever comes sooner. Obviously I’m not stock so I need to shorten these intervals, I was thinking every 5k DIY oil service and every 15k or 2 years full service

I use extractor first and then drain the rest from the bottom. Easy and clean job. BMW E91.

I change the oil on my own two cars with a sucker as the engine is designed for it to be done that way. Takes about 30 minutes to do without even having to jack the car up or crawl around underneath.

I did my OH's Freelander a few weeks back and sucked all the oil out. Then had a moment of indecision and decided to get underneath and remove the sump plug to make sure I'd got everything. Not a single drop from the sump, the sucker had got everything.

From your perspective, as you're changing it every 5k, and the sucker won't be leaving much in the sump, I'd be goign for it, it really is so much easier with the sucker. Just warm the car up a bit beforehand so the oil is a bit thinner.

God thats a lot. Its 4.6 on the older TFSI. Make the 100ml even less as a % then.


Go for it.

Thanks guys, I actually posted this very topic of a Facebook forum specific to my car, a lot of people weren’t in favour of doing this, so wanted a non biased opinion on here. Seems a lot of you guys feel the same way about it as I do smile

Yeah exactly people seems to forget how little 100ml is, thing i noticed in the videos I saw is they only used one size suction pipe, I have a few difference sizes, so I’ll work my way down to a small one to get the last few bits out

You don't necessarily need to shorted service intervals just because it is modified, there are more powerful cars on the market and there are not that many different types of oil. Providing you are using a good quality oil your standard service intervals will be fine.

That said, if you are only doing 5k a year, and the manual says changing it yearly, then it is a mute point.

As you can get to the filter under the bonnet, then I say give it a try, most people would be surprised how much oil is left when draining via a sump plug. What I would do though, is get the car warmer than you would do for a normal oil change to make the oil easier to extract, and measure what comes out and compare to what should go in for an oil and filter change.
