Title: Redex Lead Replacement Post by: MartynT on 19 July, 2023, 03:36:38 PM Hi All,
I think I know the answer to this but just checking. The previous owner of my S2 1600HF used to use the above. Is this the accepted norm for for a 1972 1600HF? Regards, Martyn. Title: Re: Redex Lead Replacement Post by: lancialulu on 19 July, 2023, 04:09:19 PM 1600 HF had hardened valve seats. So really no additive to protect the seat is required. Octane booster and perhaps ethanol protection should be considered.
Title: Re: Redex Lead Replacement Post by: MartynT on 19 July, 2023, 05:03:19 PM That’s great - thanks. Can you recommend a product please?
Cheers, Martyn. Title: Re: Redex Lead Replacement Post by: davidwheeler on 20 July, 2023, 12:59:28 PM Agreed, no lead substitute needed but get high octane petrol from e.g. Sainsbury or Tesco. Suits mine fine.
Title: Re: Redex Lead Replacement Post by: lancialulu on 20 July, 2023, 02:50:41 PM Agreed, no lead substitute needed but get high octane petrol from e.g. Sainsbury or Tesco. Suits mine fine. Or Esso Supreme nearly as cheap and reportedly 0 E even though it is obliged to put E5 on it (If I am out of date please say!).Title: Re: Redex Lead Replacement Post by: Richard Fridd on 20 July, 2023, 03:26:10 PM Did I read Esso are labelling fuel as E10 some time soon.
Richard Title: Re: Redex Lead Replacement Post by: Neil on 20 July, 2023, 05:15:19 PM The Esso E5 that has zero ethanol currently, it has been reported will actually contain 5% from September, still higher octane rating then E10.
Title: Re: Redex Lead Replacement Post by: chriswgawne on 21 July, 2023, 08:28:01 AM Yes, from September there will be ethanol in ESSO fuel. This presumably is connected with the new underground pipeline from Southampton to Heathrow which is just coming onstream.
I will still stay with ESSO 99 Octane though as it seems to give good economy and smooth running ( and I get 6p per litre discount through the Porsche Owners Club!). Chris Title: Re: Redex Lead Replacement Post by: Neil on 21 July, 2023, 08:57:17 AM I wonder if the LMC could get a discount, current price locally is £1.69 a litre!
Title: Re: Redex Lead Replacement Post by: andyps on 25 July, 2023, 09:28:52 PM That’s great - thanks. Can you recommend a product please? Cheers, Martyn. I use Millers VSPe if I don't manage to fill up with either Shell of Esso 99 Octane fuel. Title: Re: Redex Lead Replacement Post by: neil-yaj396 on 26 July, 2023, 11:14:37 AM That’s great - thanks. Can you recommend a product please? Cheers, Martyn. I use Millers VSPe if I don't manage to fill up with either Shell of Esso 99 Octane fuel. Me too, but it didn't prevent an episode of very rough running in my Beta on a very hot day at the end of June. Ran fine again after a dose of Super. I'd generally just used normal E5 and rarely bothered with Super until normal fuel was upped to E10. Title: Re: Redex Lead Replacement Post by: Paul Greenway on 06 August, 2023, 01:05:44 PM Since my Sport 1600 had it's mishap on the M6 on the way back from the GNW in April, I have reverted back to a cap full of Redex and Shell V-power fuel only every half tank and 1,000 miles + later it's never missed a beat. Title: Re: Redex Lead Replacement Post by: roddy on 07 August, 2023, 11:48:32 AM I still continue to use a lead substitute additive in Fulvias. It may be relevant to remember about the cushioning effect of a lead deposit on valve seats. Do not forget that 1600cc engines, in particular, can be susceptible to 'dropping a valve', with dire consequences.
Regards - Title: Re: Redex Lead Replacement Post by: Scott on 07 August, 2023, 02:37:05 PM I have a Fulvia 1300 (S2) and have only ever used Castrol Valvemaster Plus in my long ownership.
I guess specific product doesn't matter as much as said product doing its job of preventing valve seat recession but if anyone knows better please say! I do remember reading a long time ago the main lookout was not mixing additives that use different elements for their protection approach but that may now be redundant advice. |
