I’m looking to source original gm service parts for my 3.0 v6, does anyone know the part numbers for Oem oil, air filter, fuel filter & spin on oil filter, I’ve ordered the adapter to convert mine.
Is there any websites useful for finding the oem part numbers for parts i’ll be looking in the future?
Cheers

You will be lucky to find GM branded parts now for your Omega.
I would recommend you try Autodoc who some of us have found very good for sourcing the products we need, and recently still had GM oil available. They source parts from across Germany and Europe generally, so still offer the items previously available for Vauxhall and Opel cars, where indeed the Omega was built. ;)

None of those parts need to be GM, and because they're all shared with other models will be readily available from any local motor factor.

VOF31 springs to mind for the oil filters.

Air Filter - 91149684
Fuel Filter - 25313359
Fuel Filter clips - 90542453
10W40 Oil - 93165215

And we all know that the canister type oil filter is less messy, generally cheaper to service than spin-ons.
Granted, if some muppet hasn't serviced the car for 200,000 miles or the last idiot did it with a impact gun, then can need marginally more difficult. But day to day, cleaner and cheaper.

And the rest of us find them as much use as a used condom smeared in dogshit. Particularly if something goes wrong like incorrect part sent or parts missing. Or, more commonly, Herpes lose the bloody parcel.
Also be aware, a lot of their pattern parts make First Line branded parts to look half decent.
Buyer beware.
As Nick W rightly points out, for servicing, all parts are freely available at any factors, and most of it might even be in stock due to how many different GM vehicles they were used in. Its some of the very Omega specific stuff, not service items, that can be more challenging to acquire now.
When I had mine, I used GM filters and oil based on price and convenience (back in the old Trade Club days, so cheap, and delivered to my door same day), but wouldn't worry if I had to use non GM stuff.... ...aside from air filters, as the genuine Omega one was always deeper, hence more surface area, and also brake discs/pads as I found pattern ones couldn't handle the abuse I used to give them before I became a reformed character....

I currently use this oil in the Omega's:- https://www.smithandallan.com/product/smith-allan-momentum-ss-10w-40-engine-oil-4141 (https://www.smithandallan.com/product/smith-allan-momentum-ss-10w-40-engine-oil-4141) which comes in at a good price when you buy 20L :)

A matter of opinion TB, and I can only comment on my experiences, along with others on here, who have found them excellent after buying a number of parts. Even my Vx dealer staff use them now in the absence of GM parts. As for Hermes: you are out of date, as it is called Evri now and vastly better than than before. ;D ;D
"Buyer beware" ......well, yes, that applies to all online purchases! ::) ::)
:D ;)

Im pretty sure there is a list of part numbers for commonly used parts somewhere on here. Guides or FAQ ?
No need to dig it out now though as Jim82 has taken the time and trouble to post up his list. :y

;D ;D Indeed Ronnyd. It strikes me it is some form of snobbery about those GM parts we were so familiar with 20 years ago, and have an affinity with! No other parts are suitable in their opinion, ignoring the fact they more than do the job, being the only ones now available from reliable main line sources, as us progressives have proved! It is fact that the auto world has changed and the previous main dealer parts are "no longer available", a phrase my friendly Vx parts manager often uses now, with a roll of the eyes. After all, my Omega is 22 years old in June, being one of the "newest" still on the road, but still well out of date in terms of their production in Germany and parts availability guarantee. ::) :P ;)

Nice one, Jim :y

As for Hermes: you are out of date, as it is called Evri now and vastly better than than before. ;D ;D
You''ll note I called it Herpes. Hermes, Evri, Herpes. Same shit, different name. Evri still have an uncanny ability to lose or significantly delay stuff, as its exactly the same company as it was before, with the same processes, same systems, and same way of working.
Our local Herpes lady is really good. But I reckon about 25% of parcels I send via Herpes goes astray, usually just temporarily, but not always. About 50% get left at the pick up point for more than 3 days, which buggers my Ebay feedback when I say its a 3 day courier. One set of parcels was left there for over 10 days, and I could seem them in the heap, but wasn't allowed to recover them and send via RM.
But back on Autoshite. Most of the brands they sell are very low end. Which may or may not be an issue for some. If the stuff you buy turns up more or less when promised, and is correct, then thats fine.
My issue with Autoshite is when they do cock up (or Herpes cocks it up badly), they are completely disinterested and near impossible to deal with, even if you get a German speaking colleague to call them. And invariably, you have to jump through the hoops of going through your card company to get it refunded. Yes, you can guess how I know this. Twice. Across 3 orders.
Be aware, Autoshite run a number of different sites that are all essentially the same, as a way to get all the top hits in search engines. That should tell you a lot.

Agreed. :y
In fact very few, if any, vehicle manufacturers actually make their own filters. It’s not in their interest to do so, they just label up the packaging as their own brand.
If I buy a genuine oil filter for either of our Audi’s from a main dealer, the oil filter has the Audi logo on the end, but it also has the MANN logo on the opposite side. It’s the same when I’ve bought them for our bmw, MANN or Mahle on one side and bmw on the other. :y So, it doesn’t pay to read too much in to ‘genuine’ filters, just buy a decent brand.
-
Thanks for the help & replies, it’s nice to find a forum still with active members i thought they all died away back in the early 2000s ;D
I know any brand of stuff would do but thought it would be nice to have Gm lol, plus back in the day it used to be well priced but alot of stuff seems hard to get now which is bumping the prices up. Likes of the original red antifreeze for 5 litres is over £100 in some places. Is the blue stuff ok to use or better sticking with red from another brand?

They source parts from across Germany and Europe generally, so still offer the items previously available for Vauxhall and Opel cars, where indeed the Omega was built. ;)
Personally, I find the Autodoc (and associated companies) have the most annoying website... constantly wanting you to download their app for 10% cheaper prices - which then makes me search elsewhere. Car Parts in Motion for one have always provided good quality branded parts (if GM isn't an option for me) at competitive prices. Autodoc - no thanks. I can't stand their website.....
-
plus back in the day it used to be well priced
Back when Trade Club was running, it was a no-brainer, as it brought it all down to at or below the cheap stuff but for a decent quality part (usually!), and delivered to your door, often the same day.
Sadly, Trade Club is no more :(
-
Car Parts in Motion for one have always provided good quality branded parts
I'm a fan, either direct from them, or via their Ebay store, which ever is the cheapest on the day. Sometimes it takes a few days to turn up.
They sell Bosch pads and discs, which have become my favourite low cost brand for brakes, as they seem to be able to withstand some abuse... ...apparently ::)
-
we all have our l
preffered suppliers and manufacturers but as time goes on we will have to rely on afternarket parts more and more in the future . for service items that dont impact reliability or performance isnt much of a worry but eventually we will be using pattern crank sensors and finding which ones actually do last ( they cant ALL be useless !)
-
I use CarPartsInMotion and ACP as my go to ebay suppliers.
Mercedes parts I either buy over the counter where convenient or from MB Newcastle as their prices are generally better for service parts and fluids with Next Day Parcel force delivery included.
For the various projects any hardware and wiring harnesses are generally bought new, but the actual components from wherever I can find them, although price and shipping can make brand new cost effective.
Everything going on the Nissan is Nissan with the exception of the sealant as I couldn't find the specs for it from Nissan and they wanted stupid money for theirs so went with the Mercedes factory approved stuff for less... 3 tubes and the remover for the price of the Nissan one.
-
I also use Carpartsinmotion for a lot of parts and find them very good. :y
