Hi,

 

Any advice please:  My Toyota Avensis '51 reg has now packed in and the Octavia 1.6 FSI seems a good idea...one for sale in a garage locally '56 reg, £100 deposit paid.

 

However, having contacted the previous owner, he says it's been regularly serviced but he's always used 95 Ron unleaded (not the recommended 98 Ron).  Could this have lead to serious damage?  Everything else seems fine, drives well, 12 months MOT, but is the car best avoided?  Or doesn't the 95 Ron thing really matter?

 

Is there an easy way to tell if damage has occurred?

 

Thankyou.

 

 

 

I can't see it being an issue as the ECU would wind back the timing & richen the mixture to compensate.

 

For the previous owner the vehicle would have been a bit slow & used more fuel.  

 

I find penny-pinching like that somewhat odd.

I own the exact same Octavia and have run it on 95 with no problem and regularly exceed 40 mpg combined motoring.

Tried 98 and the difference was not noticeable apart to my wallet.

looking on the fuel filler cap it only mentions 95 and 98 on the sticker.

Thanks Brad and Jong,

 

Jong:  Do you mean Skoda have added a sticker later with 98 Ron recommended, is so why?  On another post somewhere it mentioned using 95 might gradually cause damage, but whether it's correct I'm not sure...

 

Anyone know If there is an easy way to tell if damage has occurred?  Or if it sounds and drives ok is it ok?

I have no idea if Skoda added a later sticker recommending 98 Ron on your vehicle,

 

However on the filler flap of my 1.6 vehicle it reads 95/98 Ron the Script being the same font.

 

​On my Estate 2.0 liter FSI the 98 is a larger font than the 95 so I assume in this case 98 Ron is recommended.

 

I run the estate on 95 Ron as I do on the 1.6 hatch but use Redex on both and both sail through the MOT emissions and perform

 

well, still keeping my hard earned in my wallet. 

 

 

I can only suggest the ball is in your court to make an informed decision.

Thanks Brad and Jong,

Compression test?

borescope down the plug hole to see if there's any obvious detonation damage?

 

Do the motoring organisations or similar do pre-purchase inspections?  That might be worthwhile.

As your car is fitted with a knock sensor and an ECU, I would say you have nothing to worry about.

I have no idea if a sticker was added later let alone why.

But I go along with what skodacarman posted.

If the price and condition were right and I was in the market for a vehicle then as your information, 

 

Everything else seems fine, drives well, 12 months MOT, 

 

I would purchase it.
