I've just bought some more oil for my Toyota Hiace van, the can looks identical to the last one, except the old one said mineral oil and this one says synthetic! anyone know why, or what the difference is?
 
You should use synthetic oil.
Mineral oil shouldn't be used.
You haven't bought the correct oil unless it's an old van.

Check spec and year
 
What year is van?

I think turbo runs hot and mineral oil won't take heat

What does the owners handbook say is required? This is the definitive source, more reliable than random 'netters, or people trying to sell oil.

You can look it up if you know the model, year and engine.

Lots of people jump to Synthetic even for engines that were designed before it was on the market.

Synthetic will last more miles between changes, but as it is more expensive, I doubt it is often bought by neglectful owners.

Changing the oil and filter at recommended intervals is more worthwhile than buying expensive oils.

For some reason, American 'netters recommend far more frequent changes than manufacturers. Perhaps American oil Is not very good

Clean oil is always good. But it's more important to change oil frequently on low milage vehicles as high detergent oils absorb and hold water - high mileage vehicles will boil (burn) off the water content.

You'd think the manufacturer would put something important it in the manual, but Peugeot don't for SWMBO's 2008.

I had to go on line to find what to use to top up and then 2 sites couldn't decide if it was 0/30 or 5/30. They did agree on synthetic though,

I went with the 5 but call me old fashioned: it doesn't look very oily!
 
Google search throws up this

To find out which type of engine oil is best for your specific vehicle and driving conditions, you can consult your vehicle's handbook or use the Toyota UK Vehicle Information portal. “

The important bit is the Spec e.g. ACEA C2/3/4 etc. Its those small bits that make the difference between an acceptable oil and one that meets the manufacturers spec.

Unforgiveable that such important info. is not in the manual, I've never had a car that doesn't list it, but then & again the newest I've owned was manuf. in 2006.

Maybe it's sign of the times, along with the deletion of dipsticks .. apparently considered unnecessary by marketing.
