Is there any advantage or disadvantage :-\ to using 20/50w 0il as opposed to 10/40w in a higher mileage v6 petrol engine. ;)
-
Can't see the point in the UK's rather moderate climate, also given GM's 10/40 is so darn cheap can't see the benefit?
-
That said I am thinking of trying some Fully Synth 5/30 in the 3.2, as recommended by the master as its got a noisy lifter
-
You may find it to thick for the lifters, however the straight six 24v love the stuff. My LC has done around 1800 miles since rebuild and has always been run on 20/50 but then that's what they recommend for that engine. the point I'm trying to make is they both hybolick lifters. If you are using a fair bit of oil and use fully synthetic try using semi synthetic, it seems to slow down the oil consumption.
-
my reason for the question is on start up i get a puff of smoke from exhaust (possible valve stem seals)as its a 2.6 v6 and was wondering if 20/50w oil being a bit thicker in viscocity would help with this :-\,but do understand all the comments on the lifter side of it :y
don't really fancy taking the heads off if you know what i mean,i seem to use about 1/2 ltr of oil a month at the moment and engine has 109,000 miles on it.

thanks for the reply tunnie but my problem is oil burning so 5/30 may make it worse :y

How many miles are you travelling per month? ???
-
If the problem is worn valve stem seals it will be a better option to replace the seals than to use a non reccomended oil to cure, and there is no garentee that it will make any difference to the puff of blue smoke on start up at all.

Stem seals are well known issue on early 2.6's I can see a thicker oil helping there, it may cause issues elsewhere, breathers for example?
How many miles do you get to 1/2 litre?
-
try 15/40 do not use 20/50 its to thick and will cause issues with blocked breathers,and also doesnt have the same additives to protect the engine,other option is to use stp oil treatment with every oil change :y

Thats not bad for 1/2 liter use to be honest, could be a lot worse!

I agree! :y :y

Well i think by the comments received i will stick to 10/40w semi synthetic :y

I'd try Mobil 1 High Mileage 5W-30 http://www.mobiloil.com/USA-English/MotorOil/Oils/Mobil_1_High_Mileage_5W-30.aspx (http://www.mobiloil.com/USA-English/MotorOil/Oils/Mobil_1_High_Mileage_5W-30.aspx) or Mobil 1 Extended Life™ 10W-60 http://www.mobil1.co.uk/synthetic-engine-oils/extended-life-10w-60.aspx (http://www.mobil1.co.uk/synthetic-engine-oils/extended-life-10w-60.aspx) You might need a bank loan though :).

The oil recommended by OOF is GM 10/40W semi synthetic. ;) HTH

Sorry to hijack your thread Noel.My 3ltr eleit uses 1/2 liter a month,average 1250 miles per month.Is this good or bad,140,000 miles on the clock no visable oil leaks or smells. :-\
-
I think Vauxhall Warranty says something about 1ltr/1000miles is not excessive (on new vehicles), so anything less than that on an older Omega would surely be quite good IMO.
-
Unsure how much my 203k 3.0l uses, as most of the 1/2l it gets through in 2k, most of it is clearly visible on top of the sump pan :-[

[/quote Judging by all the replies i think its normal usage,but i run a 2.6 and prone to piss poor valve stem seals. which is what im putting my oil usage down to, as i also have no obvious leaks :y

The oil recommended by OOF is GM 10/40W semi synthetic. ;) HTH
You need to read the original post. The OP is inquiring about an alternative to the 'OOF recommendation', whatever that means.
So do you thats not what he said - just to remind you op was asking if 20/50W was a sensible alternative as he was concerned about oil usage on a higher mileage engine - was advised usage within GM tolerances and similar to other members usages - so OOF recommended oil ok.
He was not asking re expensive potential Mobil alternatives which you probably have no practical experience of using (Google rules OK!!) ::)

VW consider that 1ltr/1000 Kilometers to be normal :o
My 3.2 with 246k uses just over a litre every 10k, although as TB says, most of it appears to be outside the engine ::)

Usual abuse from dbug. Why do you bother to do that?
No I don't have experience of that particular Mobil oil (nor do you) but I would try it if my car was that mileage and burning oil. That's what it is recommend for (by Mobil, not Google).
OP was asking about using an oil other than 10/40, read it yourself in his post, yet you recommended 10/40. Doh! (http://fun.resplace.net/Emoticons/Angry/BangHead1.gif)
Acceptable oil consumption is 0.97l /1000 miles 2.2, 2.6, 3.2 petrol and that's official (as in Vauxhall's figures not some 'OOF recomendation').

Calm down girls ;)

Where's a nice relaxing tyre thread when you need one ::)

Oh dear what's abusive about my post??
Reread the ops post - was only asking advice re 20/50W oil - concensus by others was that 10/40W was ok :o
There have been instances before of people recommending products without practical experience of them - that has lead to some OOFers wasting their hard earned! ::)

there is nothing wrong with your post :y. i am well aware of the recommendations of gm 10/40 but dont use it as i have no tc card,and i dont use castrol either ;) but thanks for your input as any info is helpful to me :y
-
If you don't have access to TC, either join Autobahnstormers, the £20 joining fee pays for itself almost instantly.
Option B is contact AndyC, he is parts Manager at a Vauxhall Dealer, he can get you TC price or better :y
Usefull for other parts, problem is with oil is weight of course, still think his price delivered would be quite good :)

I was in Costco the other day and they had 20ltr Chevron 10w40 and 5w30 for about £36 or so. :)
Anyone any experience of Chevron oils? ??? Obviously not in an Omega though.... ;D

I've used it. Seems to do the job.
