Unleaded
 

Heard from Nissan that I should only run my S12 on unleaded as it may damage the engine ?!

True or not chaps :eek:

diesel mate, thats the best.

as long as it is 97ron or above

originally nissan said that the S12 can only run on leaded 4 star, ive had my S12 now for 8 years, always run it on unleaded. it wont damage the engine as the valve seats have the inserts same as used in unleaded heads, the only other thing that can cause a prob is the timing, some say you need to reatrd it slightly. i think 2 degrees was the amount, but unsure on this.

most people use tesco 99ron super :D

It even says unleaded on the inside of the petrol flap:)

Say's use 97ron unleaded on my petrol flap.

i use shell optimax, or what is now known as v-power.

Posting when drunk = no no lol but you know what I meant :D

Cheers chaps was getting all worried then !

So is it best to run with it retard a few degrees ?

Just make sure theres a retard in the seat and you shouldnt have any problems:1la ;)

i thought you ran on ronnie corberts adz

i wouldnt bother retarding the timing it will lower performance + generate more heat, the standard timing is 15deg + or - 1 deg. i used to run 17.5deg as it gave better off boost performance but i never use less than 97ron fuel

Standard timing will be fine and it will run normal unleaded for long distance commuting, If you intend on putting your foot down or are running a modified setup then use super unleaded. Also Shells new v power contains valve lubricant which is good

Cheers then chaps :)

Lol yeah i do but thats our secret fuel, you can buy a bottle of ronnie corbet additive from your local motor factors, just say ronnie barker recomended it;)
