hi people what type of oil do we all use in the vg30dett

thank

It's a topic that has been discussed many times mate, have a search and you will find loads of advice.

manual suggests 10w/40 take a look at some threads, though oilmans threads contain a wealth of info

Sound advice from Chris as always!

 

This topic always yields several different replies as everyone has their own opinion or preference. But as Chris says, stick with a decent 10w40 or 5w40 fully synthetic and you won't go wrong!

as always you all come up trumps will be in the gge again tomor so will jry and put some pics up for you all

thank's

There are some good 5W50 and 10W60 oils out there, which are very good at maintaining their viscosity at high temeperatures that they get to going through turbochargers.

 

It is a can of worms but changing it regularly is just as important as the spec.

 

My zed has been run on 5w50 for the past 7 years and prior to that castrol 10w60 for the 2 years. Its now on 160,000km which is about 100,000 miles and still on her factory turbos! touch wood.

Hi Berks where you been matey !!

Eh up jimmer, not been on for a few years due to winning the lottery and didnt want you lot crowding round me with your begging bowls!!!

 

Seriously tho i just been busy with work and dont often get on the net at home, but since nextdoor got wifi ;-)

10w40 mobil X semi for the win.

 

I wouldn't personally run 5w40 fully in a higher mileage old engine, it shears easier than a good 10w 40 at higher temps and won't stay in grade as well. Although in theory it gets around quicker at start and low temps, the additional flow is negligible in my opinion, I'd rather have something a little thicker to get be in the engine and around those increased tollerences.

 

 

Cheers,

PS, you may find thinner oil gets passed the seals easier in older tubbies etc.

Wow - another blast from the past! Hey Steve - hope you're well mate!

 

On the oil subject - my understanding was that the higher number relates to the viscocity/stability at high temps; so a 5w40 is the same as 10w40 when warmed up and running...?

Hi Mate :)

 

I pop on here once every few months to check the for sale section to see if there is anything interesting around.

 

I stumbled into the advice forum and thought I would post up.

 

And in theory yes, 5w40 is the same as 10w40 when warmed up :)

 

I had an interesting scale, can't find it right now though, it showed how different multi-grades stayed in grade at over 80 deg. Brands differ as does the difference between grades (IE 0w or 5w 40 don't stay in grade as well as 10w 40 at higher temps). I believe the industry standard is to measure up to 80 degress to achieve the high temp rating we see on the labels, some motors run oil at around 90 (eg mk2 golf's run at 95 oil temp IIRC).

 

As contaminents get in the oil through use, the oil also breaks down and it affects the ability of the oil to stay in grade also meaning it will shear. Combine a thinner base oil with a few k use in an older engine, and in my opinion it won't protect as well.

 

Still that's just my opinion :)

 

I moved from 5w40 to 10w40 in the Porsche for added protection, oil pressure is a little stronger, but all in all, either seemed to do fine.
