Yamaha Fan posted that 2 stroke oil increases the octane rating of diesel which effectively is the same as reducing the cetane. High cetane fans on a local forum down here, used this to discredit the benefits of 2 stroke oil Good news about the effects on the DPF, atlas |

Hi atlas thanks for sharing that with us. Please try to switch to JASO-FC 2sO, as the fully synthetic FD variant can block the DPF over time. Your observation regarding the extended burn free cycles when using 2sO is quite correct. For those not yet fully up to speed with the 2sO issue, the more solid combustion residue particles are produced, the QUICKER the the DPF will have to go through a regeneration cycle. So that should be an eye opener.

Hi atlas Fully synthetic JASO-FD 2sO's are mainly formulated for very high performance 2-stroke engines, where ash free burn is less of a criteria. Critical here is the guaranteed lubrication for up to 18'000rpm and in some cases even higher. Due to that, the additives added to JASO-FD are not DPF friendly.¨ I hope this answers your question.

As we are a friendly bunch, any JASO FC for a DPF vehicle and JASO FB for non DPF |

This is the stuff to get currently at Tesco at £1.48 per litre, though hve only found it filling stations not the stores so far. JASO FC spec so can be used in both variants.

The only reason to get FB is if it is cheaper. FC will work just fine in a non-DPF engine as well. Also, the ashless oil used for 2 stroke outboards (TCW-3 spec) works just fine with diesels as the Nth Americans use this a lot ('normal' 2-stroke oil is a rare commodity over there due to emmision restrictions limiting the sale of the vehiciles that use it ) |

In this country you would be hard pushed to find FC cheaper than FB, hence the quote. |

Been on to Mercedes Website today, to see if there is anything in the G-Class user manual, since my last post back in March 2011, just after Yamaha Fans claim that 2SO was an allowed additive
which i have googled this list of approved improvers
Not sure what or if these are manufactured additives that are supposed to be the same as 2SO |

googling each of those additives they are all cold weather type additives, so my guess is the search continues for this elusive 2SO statement |
