Wondering if anyone has used Aztec Torotec 5w-30 FLR c1 Engine Oil.?

One of my local Indys is using it and saying they have had no long term issues with it.
ACEA C1
Ford WSS-M2C934-B
Jaguar Land Rover STJLR.03.5005 (Recommended for use)

Its very low cost vs Ravenol FLJ which I use now and Fuchs Titan GT1 Pro C1 with another local indy uses. 2012 SDV6 HSE Lux

It's going to not be as good as say "Castrol" or "Mobil" but is a lot cheaper. It will meet the technical requirements so will it be ok? Yes it will. Will it provide the same level of protection as it ages, probably not but what it does provide should still be adequate.

The challenge is the same as you have with tyres. Officially a budget A rated wet tyre will perform similarly to a Pirelli at 3 times the price and most of us will never be able to tell the difference. But that one winter's day on a wet motorway, when you really need those fractional differences, will you regret it? It's a quandry we all struggle with.

I always used Millers on my V6 which was also much cheaper than the premium brands. But I was running it in a Jag XF which, is a lot less stressed. You rarely heard of spun bearings and snapped cranks on XFs. The RRS is a very different animal. If you do changes every 5k or so, or don't intend to run the car for the long term, then it should be fine, but if you tend to stretch it, then given the well documented foibles of the V6 Diesel on the RRS, all of which seem to relate to lubrication, then for the minimal cost difference, I'd go with a premium brand. 2021 L494 D300MHEV Autobiography

i use petronas 5000 fj, although recently bought quantum synta z both approved by land rover c1 oils.

I've just flushed my 3.6 tdv8 with Liqui Moly pro line engine flush (1 litre).

Oil wise I used Liqui Moly Special Tec F 5w30 fully synthetic oil, with 2x 300ml of Liqui Moly Ceratec.

Best oil I've come across, I used Millers last year, but feel the Liqui Moly is superior in spec.
