What oil brand/viscosity for 2017 1.4T please ?

Post by SimonR » Sat Aug 01, 2020 2:11 pm

Hi All,
Just bought an Astra 1.4T 16V 150 Elite Nav 5dr 2017 and I am struggling to work out which oil to put in !
I have found out from this forum that it should be Dexos 1 Gen 2...........but then further reading lead me to a change where somebody states that Vauxhall have changed it to 0w20 ?
So I would be really grateful if somebody could suggest the best oil to use in it please, including brand would be helpful, Opie suggests either Millers or Total, but again they are 5w30 Dexos 1 Gen 2, so not sure what to do.
Have tried a search on the site here for best oil brand/viscosity, but the search engine removes the word "oil" as it is used too often, hence I can't find much !
Thanks very much, Simon

Hi
You won't go wrong sticking to vauxhalls own Dexos 1 Gen 2 5w30 oil.
Now there is an oil service bulletin that indicates it is mandatory to us 0W20 oil on the 1.4T manufacture year 18 and older. So on that basis yours is the 5w 30 D1G2

This has been posted on the site

..... hey thanks very much for your speedy informative reply.
Could you suggest any other specific brand that people prefer/rate on here please?
I had a Corsa D 1.7 CDTI before this and used Fuchs Titan GT1 Flex 23 5W-30 in it........used for 8 years and 85,000 miles with no problems, so I really rate Fuchs and would like to use them.......any views?

......my car is being delivered on Wednesday, so I'll see then what's on my cap then !
Thanks Neil
Ok, thanks again Redman, I might use a gallon of that GM stuff to give it a bit of a flush for a couple of hundred miles or so (because I don't know it's history) and then that'll give me a chance to find something I'd prefer maybe....?

I’m sure I read a VX tech doc stating the new oil is for cars fitted with a GPF and ones without should continue with 5w30 Dexos 1 Gen 2. Don’t quote me though as I read lots of them so might be confusing it somewhere...

That had entered my mind, but the 1 litre engine appears to be able to use the 0W20 oil what ever manufacturing year it is. So the 0W20 oil is backwards compatible with that engine but appears not to be with the 1.4T engine. So both engines at some point have had GPF introduced.

According to the owners manual you can use either oil on the 1.6 with gpf.
At the time of issue of this owners manual the 1.4t gpf version was listed as D1G2 only. The service bulletin has since changed that.

I have also commented about vauxhall's inability to get things right, on a previous thread, with regards to oil type clarification. The owners manual 0W20 oil type number is listed with too many zeros when compared to the bulletin.
