Fuel Additive…..Sorted. (1 Viewer)

[Larrynwin]

My petrol Rio toad has for some time had an intermittent brief misfire on low revs when accelerating gently with management light flashing intermittently .
Had it checked at garage also on my obd reader and shows occasional misfire on cyl 2.
I considered changing plugs , leads and ht coils but when reading manual, fuel additive is recommended every few thousand miles so put a bottle of STP additive in tank and problem gone, sweet as a nut now.

There you go, it’s not all snake oil as said by others. Cheap fix

Glad you posted ,

only last week I was tempted to buy fuel additive for my recently purchased 2018 Skoda Octavia , 1.4lt petrol engine..

your post prompted me to look in the owners manual for advice..


CAUTION
Petrol additives (additives)
■ The unleaded petrol in accordance with the prescribed standards meets all the conditions for a smooth running engine. Therefore, we recommend that you do not add any fuel additives to the petrol - there is a risk of engine dam- age or damage to the exhaust system.
■ The following additives and auxiliary products may not be used - there is a risk of engine damage or damage to the exhaust system!
■ Additives with metal components (metallic additives), in particular with manganese and iron content.
■ Fuels with metallic content (e.g. LRP - lead replacement petrol).

It also had the same advice for the diesel engine models

CAUTION Diesel fuel additives
■ The diesel fuel in accordance with the prescribed standards meets all the conditions for a smooth running engine. Therefore, we recommend that you do not add any fuel additives to the diesel - - there is a risk of engine damage or damage to the exhaust system.

Now that’s the opposite to what Kia recommends.

I find filling occasionally with the premium fuels works however it’s only a higher octane and not an additive But seems to give a smoother running engine

Likewise..

I put in the odd tankful of Shell V Power..

according to the Skoda manual >>

On vehicles using prescribed petrol of min. 95 RON, the use of petrol with a higher octane number than 95 RON can increase the power and reduce fuel consumption.

Yes I found it helped with mine but didn’t stop the occasional hesitation which the STP did.
