Is E10 Petrol OK to use in Toyota Carina E 1.8GS hatchback registered in March 1997 with 7AFE engine?


Recommended Posts

The DVLA E10 fuel checker GOV.UK - The best place to find government services and information (check-vehicle-compatibility-e10-petrol.service.gov.uk) confirms the following for all European Toyota vehicles:- 

E10 petrol is cleared for use in all Toyota European petrol models made from January 1998, excluding:

  • Avensis 2.0 litre with engine 1AZ-FSE made between July 2000 and October 2008.
  • Avensis 2.4 litre with engine 2AZ-FSE made between June 2003 and October 2008.

Question: I have a Toyota Carina E 1.8GS hatchback registered in March 1997. It has the 7AFE engine. Does anyone know whether my car is OK to use with E10 or will I have to use the more expensive E5 Super Unleaded.

Hi Frosytballs,

I looked at the link you kindly provided. The website advised that I should contact my local Toyota main dealer. I contacted the Kingston Toyota branch in Surrey and, believe it or not, the young lad in servicing was not aware of this new E10 fuel and the impact it could have on older vehicles. So I provided him with more information on this issue and he was grateful! He was completely oblivious to it. However, it still left my question unanswered so he promised to contact the Technical gurus at Toyota HQ and get back to me. He got back to me today as Toyota HQ responded to my question. Their advice - "they do not have any test data on vehicles older than 1998. Toyota may revisit this" but the young lad was not certain when. His advice was to continue using standard Premium Unleaded (95 RON) until it's withdrawn, then use Super Unleaded (97/98 RON) thereafter.      

More expense for a perfectly serviceable older car!

When you begin using super unleaded, have a loom at those supermarket filling stations which have super unleaded, which may bring the costs down a bit. For example, at our local Tesco Extra super unleaded is currently only 6p per litre more expensive than unleaded, plus it has a better additive package. Whereas our cheapest branded super unleaded (Esso) is currently 12p per litre more than (Esso) unleaded.

Since the Carina has a similar 7A-FE engine to the Mk1 Avensis, so long as most of the fuel components are the same, there is a possibility it is compatible! I say with caution, because there could some differences. The Avensis (97-99) with the 7A-FE is 'cleared' to be used with E10 fuel, but strangely the later AZ-FSE series is not! The AZ-FSE are direct injection engines, and other direct injection petrol engines of the time from Ford, Mitsubishi/Volvo, Vauxhall and VAG are also not compatible. Same for a lot of carburettor cars.
I hope my theory that 7A-FE is compatible whatever the installation. For now it will best to use super unleaded E5.

Here are some earlier posts on the subject -

As well as the above recommendations, this AA link might give a slightly broader overview of the E10 'problem'.

https://www.theaa.com/driving-advice/fuels-environment/biofuels  Perhaps you've already gone beyond this?

In the absence of recommendations from Toyota GB, as a 'long shot', then you could consider this line of inquiry:  E10 petrol has been on sale in, for instance, France, for some years now.  Toyota cars are popular over there (and some milder areas may avoid the road salt corrosion that blights some older UK cars, so they will theoretically last forever! 😁).  There must be Carina owners who have had the same question as you, but some years ago.

Perhaps there are some recommendations, or practical experience, on their Toyota forums?  Google translate is a pretty useful tool here...

Toyota France (a separate company to Toyota GB) may have been more forthcoming with information, too.
