Hi Guys,
After being a regular reader of this
forum for several years this is my first post. Here goes!
Yesterday I phoned the local diesel specialist to make an appointment to get my 93 GQ TD42 injectors cleaned up. He said they were booked up for two weeks. Why I asked? They are flat out fixing injector pump leaks. When I pressed him on why the rush on
fuel leaks he didn't seem to think it was anything to do with the so-called 'Winter
fuel' from BP - but he did volunteer that most leaks were on vehicles earlier than 1996. I asked if
fuel additives helped - he didn't have an opinion.
Then I did a search on this
Forum for comments on additives and found quite a lot of comment from a year or more ago. Some are using additives such as Flashlube, Morey or Chemtech because of the claimed lubricating properties which could protect the mechanical pumps and the seals.
One contributor said that BP actually add a lubricant to the new Ultra Low Sulpher
Fuel which was interesting. So next I sent off a question to the BP Technical Help line and almost immediately got this reply.
quote:
1. Diesel
fuel lubricity; a test is conducted for
fuel lubricity as part of the Australian Standard for automotive diesel
fuel. BP diesel meets this standard. When the
fuel is tested, if it is low in lubricity an additive is added to the
fuel, if the
fuel already meets the lubricity specification then no additive is added.
2.
Fuel pump leakage; this is typically due to seals becoming brittle and breaking or seals swelling. These can be the result of either seal degrading due to wear and tear, but can also be exacerbated by the solvency of the
fuel.
Thought that might be of interest to the
Forum!!
My question to Forumites with pre-96 vehicles and using a
fuel additive: have you had
fuel pump seal failures? Should I be using a
fuel additive to help stave off what seems to be inevitable??
Look forward to your comments.
Max.
