Is it cheap for a reason or just good value?
I believe that it is probably (as you say) good value, after all, it meets the same international spec as other (major) oils. I doubt that they would last in business very long if it wasn't up to the job. IIRC, Comma take used oils and refine them before re-selling.

I've used comma oils for years, never had a problem with them.
Ok, i may be a bit biased as most of the motorfactors i've worked at have stocked most of their range of products.
My Chim goes into Racing Green for it's services, so i only top up with Comma Motorsport 5w-50. But i would use Comma oils.
They do have a good range of gear oils with a all sorts of specifications.
as long as you get the right one you will be fine.

They also have an application guide on the website.
(but it doesn't cover the later Tiv's.
)

I believe they got stared by recycling old oil,
But that was before i even knew what oil was.
Yes, they are now owned by Esso.

What Comma doesn't really want you to know as it's traditionally a family business (and I hope they won't shoot me down in flames for mentioning it) is that they are a full subsidiary of ExxonMobil and thus have no problems in getting the proper base oils and additives for their products - unlike some of their competitors (the worldwide market has been really tight for quite some time now as older plants are being shut down with nowhere near enough new ones emerging to keep refinery capacity up with demand).
If they have the correct spec for the application, I'd have no hesitiations at all to use their products.

why do people keep going on about high performance, its over a 50 year design .every one i know with classic and kit with this engine fitted uses 20*50 oil ... nice and thick for old engines (vr1)
The TVR v8's been to TVR Power for a bit of fettling before being installed in the car, also I think you'll find that your average 1960s Rover wasn't running at anywhere near the temperature, revs or performance that our TVRs are, that's why a synthetic rather than mineral oil is specified.
Use a 20/50 if you want, but I wouldn't buy your car off you

ive done a bit of research and Comma oil is as good as any other brand very surprising!!!!!!
***As good as any other brand that uses Group III base stocks for their synthetic oil.Group III synthetic oils only use about 12% synthetic base stocks. The rest is hydrocracked petroleum base stocks. For major oil companies who have their money in crude oil refining, the word "synthetic" is merely a marketing term. It does not mean 100%, but just that a percentage of synthetic base stock goes into their product. Most "Fully Synthetic" oils are not 100% synthetic.
Some brands use 100% synthetic base stocks, so Comma, like Castrol (who make SynTec out of Group III base oils, that is highly purified mineral oil with most all of the cockroach bits removed) cannot be as good as any other brand.
Not a TVR but I use Comma Motorsport 5W/50 in the Boxster, it is SL spec rather than SM & means it has more ZDDP which having run a tuned RV8 in a TR7 is important for cam life. Not sure if the RV8 in a TVR runs much tighter clearances but I'd have thought that the 5W/50 is ideal, rather than a 10W/40.
