[VXL V6]

So now the supply of GM 10W40 has, errrr, dried up, i've been looking for a cost effective alternative.

Kevin had mentioned a supplier on another thread and looking on their site it appears this would meet the spec:-

https://www.smithandallan.com/product/smith-allan-momentum-ss-10w-40-engine-oil-4141

Tempted to buy 20L at that price and see how it goes. Any thoughts or anyone used this before?

GM was available from Holland for sensible money...

[VXL V6]

Think i'll stick with buying from a supplier in this Country to be honest, happy to buy from parts from Germany which aren't available here but Oil seems a bit overkill

I've bought 20l of this oil for the Omegas from Smith & Allan and it seems fine. Difficult to say anything other than that - the engines run sweetly on it, no mayo in the filler neck, and they've ve not gone bang....
It is the correct API and ACEA rating for the Omega too.
I did look at Mannoil too, but I wasnt convinced,  and I steered towards the Smith & Allan from past experience of their oils.
I've have also used their ATF and EP90 gear oil in my Triumphs and it has been absolutely fine. I would not hesitate to buy more when the time comes.
Their prices seem pretty good too with very quick delivery.

Thanks, I've gone through the same thought process as you, Manoil kept appearing in my searches based on spec / price but this independent supplier seems a better alternative and also I like the idea of supporting a small business.

20L ordered

[johnnydog]

Good choice, I think

I use whatever is cheapest in my two that meet the spec.  Which tends to be Mannol in one and Fanfaro (who?) in the other.

The Omega isn't that fussy, aside from oils that absorb lots of moisture.  So, VXL V6, let us know if it has a tendeancy to leave mayo on the cap when you try it

Use liqui moly stuff for mine, the 10/40 one

I use the Liqui Moly Top Tec 4600 in the BMW and Liqui Moly Special Tec V in the Volvo, They are good quality oils but I try to purchase them when there are discounts are available from places like https://worldoflubricant.co.uk/ or if there are better deals from the likes of eBay (Arnold Clark's eBay store sells it cheaper than most at the moment).

yes i have noticed that the omega does tend to produce mayo but luckily due to the design it collects up in the (removeable) filler neck so easy to clean out now and again. not helped with mine with short journeys but it has had gm oil in for the last 3 changes.  be nice to know if other oils are better / worse in this matter .ive heard that castrol is bad ?.
mannol will be my next choice especialky at around £45 for 20l

The mayo also tends to form in the breather system as well.  Hence needing to keep away from oils that are susceptible

That is what I found, too, frozen mayo in my breather system created much work when parked outside after short journies in -22 degrees Celcius, now changing cam cover seals.
How about Mobil Semisyn 10W40. Does that fulfil Omega V6 Y26SE spec, actually what the spec is? API SL?

That oil in your link is suitable for petrol and diesel engines, and appears suitable for the Omega relative to the API rating.
GM oil for the Omega was SL rating but a higher rating is ok to use, but personally, I would try to stick with as near SL as possible as the engines are now quite elderly and modern engines have progressed.
This link goes a long way to explain oil specs.

Equally, I don't suppose much harm will come from using oil of a higher API rating....but there is also the ACEA rating to consider too!!

[polilara]

Thanks, good enclosure, never knew that S is Spark and C Compression Ignition. Now question is only the mayo thing.
