Synthetic Or Mineral

[caspardog]

Hi All - first post on here and a really stupid question, but I need to know the answer.

I have a W reg, Year 2000 Toyota Avensis 1.8 Vvti. When I do an oil change should I put in synthetic or mineral oil (or semi synthetic)? If it makes a difference the mileage is coming up to 110000.

I don't think there is a definitive answer to your 'really stupid question' (as you put it)

The oil companies would have you believe all sorts of marketing hype if you listen to them, but I believe that as long as you use a good quality oil, of the right grade and specification for the car, then it's down to personal preference for which type you use.

Personally, I always use a semi synthetic.

Use whatever your car has always used. This is the advice I got when I asked a Mr T mechanic what I should use.

Apparently Toyota recommend Semi Synth but if you have always used full synth then you are fine to use either. I've always used Mobil 1 because the showroom I got my car from always put Mobil 1 in cars. On the occasions that someone has put semi synth in I have noticed the engine starts to sound rough in about half the time it does using fully synth.

Any decent brand name 10w40 Semi Synthetic will be perfect for your car, its what Toyota dealers recommend (and use).

I recommend Millers XSS 10w40 Semi Synthetic, its around £15 for 5 litres, superb stuff!

I used Toyota Genuine Motor Oil 10w40 Semi Synthetic and Filter at last service, was around £22 for both!

I wouldnt use any thinner than 10w40 on a vvti with 110k!
