Oil top up

forzacalcio

Stupid brain freeze here..Have a 1.6 2007 Jetta. Normally used to throw in 10w40 but in a hungover state at petrol station Im seeing that I should be using 15w40? Is this correct?

What's the best to do here. I'm 99% sure I have 10w40 in engine. Should I just keep using that or switch? Long trip today so no option to drain what's in there etc.

If your only topping up a liter it shouldn't make much of a difference, I'd go with the 10/40. Car shouldn't blow up.

If you ever put a few quids of petrol in a diesel by mistake just fill the tank to the top with diesel and you'll get away with it as well, think it even helps every now and again.

Cheers for that. Yeah it's petrol so no fear of putting wrong in :-) Just oil I had a brain freeze but assume it should be 15w40 after full oil change going forward?

It's fine for now. Do change the oil properly when convenient.

It's the specified oil type is what's important, so just make sure that's ok at least.

Yeah formula 10w40 was the one. Ill ise that thanks for the replies all.

Strange that total is 7 euro in centra and formula is 12 euro in topaz. Assume just shops hiking price? Always thought Total was a good brand

Check the owners manual, 15w40 would seem a bit viscous for a modern engine on a cold start. It'd generally be more appropriate for much older engine designs, very high mile engines or really hot climates.

Don't automatically trust something you see in a petrol station, it could be referring to a jetta 30 years older than yours.

It didn't even say Jetta. It said all petrol cars 2005 upwards for 15w40. 2000-2005 10w40 and before 2000 use 5w40 outside topaz. I'm at the stage now I'm second guessing what actually I put in last time. I usually leave last bottle in boot for reference but cleaned out car yesterday and dumped it without looking

I'm talking more ACEA type, A1, A2, A3 etc.

Ignore it, its nonsense, check your own manual

I was once given a bottle of something in a garage and assured that it was ideal for every engine... Luckily I was only topping up.

That sounds completely assways.

5W30 is recommended for this engine both Passat and Jetta using it.Change next time for good oil.10W30 itd if you would live in Spain for example or have high mileage(only if engine would losing sealing and take too much fully synthetic oil)
15W will kill new engines too high density and won't lubricate enough when starting,results are seen after few years.

You must be taking that sign wrong surely.
I can't believe anyone could publicly print such incorrect advice.
Don't get 15w40.

1st of all DO NOT put in 15w40 to a 2007 Jetta, this can seriously damage cat convertors, oxy sensors, etc.

I've attached an oil guide link where you can input your registration to find out the correct oil for your vehicle as stated by the "experts"

Just to let know some drivers:
Its good check for newer cars but if you put 20years old car it shows you original oil used i "light' conditions.If someone used **** like 15W on old engine and its taking oil,losing compresion etc etc and look at this might to change on 5W30 that would be a bad idea.
Other than that good site and quick way to get info for many drivers.
