The Land Rover I have, may be old, but she run’s just fine on a combination of veggie oil, biodiesel and diesel. This gives me a good choice on how I fuel the vehicle and how much I pay to fuel the vehicle. With WVO being a premium now, I am finding it ever more difficult to get good consistent sources; and then why I do find something it ends up being 50% bit of crap and 50% WVO. SVO is not my ideal choice, not only for ethical reasons (we cannot produce enough of it), but also the added things like anti-foaming/gelling agents don’t help combustion. I’ve no evidence to suggest that they are removed when used as cooking oil, but the stuff I use as WVO always seems to make a smoother sounding engine. So I’ve been testing Cetane boosters to see how effective they are with SVO and to see if they take some of the knock out of ordinary SVO.
First up is the Diesel Nitrox Cetane Booster. It claims to do the same as the much more expensive branded products. It’s one of those bottles where you have to guess a bit on how much you add, but if your doing a whole tank full it’s quite easy. It worked well and certainly reduced the diesel noise as well as appearing to give a little more performance. Nothing scientific here, it’s all perception. For the money it’s easily the best available.
For a few pounds more, you can get Millers Oils – Diesel Power Eco Max 500ml. It claims similar things, but suggests it boosts the Cetane number by 5. It’s much easier to measure how much you need to add with this bottle layout and it did just as good as job as the cheaper product’s here. It doesn’t claim anything fancy, but suggests your car will be more environmentally friendly by using less diesel and putting out less emissions. There is a tentative link to the claim, but your not saving the environment with these products directly, just helping WVO or SVO do their job better.
The last one is Morris Superclean DD. Nothing on the package to show it’s a cetane booster, but it’s in there. No claims on how high you can boost it by either; just simple honest – “this will make things a bit better” marketing. Give them credit for that. They seem to be a UK company too, but I can’t see where the product is manufactured. Like the others, it did what it said on the tin and was definitely better than nothing and as good as the others. Like the Millers Oils product, it has an easy measure which makes it a lot easier to use.
Search around for the best prices for these products, but they are all around the £7-£12 bracket for their standard size. So which one do I use? I’m sticking with Morris Superclean DD as it’s seems a good working product, with an easy measure and it does what it says on the product blurb.
Found anything better? Let me know and I will try it out.
