Of course, all petrol 98ron is unleaded. Do you add lead replacement?
I use ethanol free in my 84 QV. Easy to find in Florida not sure about Belgium. Otherwise pretty much any unleaded should be fine.
Pretty sure you dont need to worry about adding a lead supplement to your unleaded fuel for a 328. I understand the valve seats in all 3x8 engines are hard enough to not need the lead. Also your 328 probably has a catalytic convertor which do not play well with lead in fuel. Sent from my iPhone using FerrariChat
The engine is designed to run on no-lead, evidenced by the (required) presence of a catalytic converter. No additives needed. Been using "normal" pump gas (w/ethanol) in my '89 328 since I bought it in '08. FWIW, I ran pump gas no-lead and later no-lead/ethanol in my 1968 Plymouth Barracuda for nearly 20 years with no hiccups whatsoever. No additives ever.
U.K. and EU based here - use E 5 and highest octane .Shell do a 99 but most others do a 98 , even used 97 when that’s the highest availability .It’s a carbed GT 4 from the 70 s . Might be worth mentioning I don’t cane it .It’s sympathetically driven *So in terms of cylinder temps / pressures and valve impact speeds etc etc it’s getting an easy life .If you are continuing to bounce it off the redline then I guess the fuel chemistry might come into play re valve seat longevity. * once a guy on here with 3#8 packed with go pros did a canyon run .Lots of redlines and nice tubi exhaust noise etc .Got the footage professionally edited and nice music etc . For the majority of the vid there was a VW golf ( rabbit ) in the rear view mirror .Ok now and again it’s distance semi receded but you could always see it more or less . Came to a stop light and the VW pulled up close as they do waiting …..it was driven by a granny coming back from the shops . From then onwards I never thrash mine .Pointless theses days .Just saying .
Thanks every one. In Belgium we have only a choice of 95 en 98. I asked because i have a Lancia Montecarlo to and that one realy needs the 98 + lead adh. My 328 is as mentioned a 86 Euro version so he has no catalityc converter or ame i wrong in this?
Whether it had a Cat on it originally or not, I can't imagine that Ferrari installed one type of valve seats/valves in Euro cars to use leaded fuel and a different type of valve seat/valves in US cars to use un-leaded. Would make no sense since the better valve components (for unleaded) would work fine for leaded but the opposite is not (theoretically) true. But, as I said, I ran a conventional US V8 on unleaded fuel for 20 years with no valve head/seat issues so I have always wondered if the concern is a bit overstated...
NO. Period. And this is "official from Ferrari", as there is a kind of "service bulletin" from Ferrari in the '70s, that has been posted here quite a number of times which says that, starting with the first V8 engine (carburatted, 1973) there is no need for any lead additive whatsoever in the petrol for their road engines (as for race engines, I don't know...). The recommended "euro" octane rating by your" Owner's manual" is 95, although the cars run well on 98 also. Both my '89 euro 328 have been running on 98 for 16 years now. And of course no lead in that whatsoever. Rgds
How about fuel w/ methanol or ethanol additive 95/ 97 octane is it safe to use w/ our 328 ‘s ? Here in the Philippines pure gasoline 98 octane is available but not in all gasoline stations
Does not need TEL aka lead because the aluminum heads had hard valve seats installed when they were manufactured. It was mostly an American thing because in the USA most cylinder heads were cast iron without added valve seats.
