Good day guys! I recently bought a 2009 L200 ( new shape type ) and I notice that whenever I put in a full tank of Bio-diesel, the truck would be very hard to start. It pretty much acts as though it cold starts each time. And I notice that it is not a problem which happens time after time, for example.
Some mornings I would start the truck fine, now even though I drive and drive a lot then go park… I can come back to the truck like 30 mins-1hour later, and the truck might start on the first swing of the key!....other days it can take forever.

I have changed the Timing belt, balance shaft belt, changed ALL filters, and changed all liquids and oils, but this has me starching my head.

Because whenever I use regular diesel form the gas stations it does have the issue, only when I add biodiesel.

And yes of course! I allow the glow plug light to go off before I start turning the key.

Any help would be appreciated, thanks in advance.

Oh by the way, I don’t live in the UK. I live in Barbados. The fuels we get here aren’t as high quality as some places in UK, but its still pretty decent. And i forgot to mention, Im not having any check engine lights turning on.

welcome from barbados mate, bio diesel 100% is probably thicker than 100% regular derv dont quote me on that though

did they set the timming up correctly could be a tooth out or did they knock the CSS when changing belts

also check the glow plugs for resistance just because the light is on dont mean they are working not that you should need much heating up out in barbados aint it hot out there

How fresh is the bio? Once made it will not last forever before it starts to thicken up. Any oil deposits would set in the fuel line much the same as in our bodies. Sounds like you might have a small deposit somewhere in the fuel line. Have you got time to flush them through?

Proper genuine biodiesel in the UK is chemically quite similar to dino (albeit with a few aggressive chemical nasties), and similarly viscous. What is biodiesel like in Barbados? Is it proper diesel made from plants, or is it closer to vegetable oil?

Probably made for all that waste oil and stuff they use

Bryl Creem?

could be from the grease traps in the hotels

Indeed, and if that's the case one wonders how refined a product it might be.

well they also like fried food out there mate

how well is the WVO processed too

I process mine pretty well, but its not a hardship as I only use about 80 litres a month.

i know u would mate its ur pride and joy that it is going into

but on a smallish island with limited resorces running a buisness how well would the suppliers actually process the WVO

Keen cyclist, so don't do the miles. Even keener now I'm recovering from a heart attack.

he only uses 40L in the truck other 40 he cooks with or drinks

Hey the diesel here within Barbados may not be the best, and one thing they all have in common is, they all using the oil from fast food restaurants. So even if you go to someone else you getting basically the same.

Since i've stop using it, and filling up with normal diesel the problem doesn't happen to often, but its still there from time to time.

Jay new common rail engines dont like WVO really
I guess it depends on what they have done to that oil to make it into bio fuel

Errrrrrr. Hate to say this but I wouldn't be using Biodiesel from used cooking oil on a new shape engine.
You have a commonrail fuel system which is MUCH more sensitive to the substance it is pumping. Used cooking oil is going to have, as well as plant oils, animals fats, a high percentage of water and depending on the process your suppliers are using, any number of thinning chemicals which can be very aggressive.
thicker fuels can and will cause excessive wear on your injectors which are not cheap to replace and the animal fats can congeal and damage you fuel pump as well as coat your fuel lines.

My advice would be change your fuel filter(as it is probably full of bits of batter!) and stick to diesel in the future. Or go ahead and process your own fuel. that way you can know for sure that it is dry, clear and clean.
