5w30 or 5w40?

[StatedRain]

Normally I'd pay a garage to do the service on my car but money is tight so I'd rather save a few quid and do it myself, but I'm struggling to find a definite answer for what oil I'm supposed to be using Haynes manual says 5w40, europarts recommends 5w40 and 5w30, having a look at previous posts etc it seems both are recommended, car is 1.9tdi 140k miles bxe engine code.

Big difference in price there, is there any reason why 1 is so much cheaper?

Edit: didn't realise 1 was 20l and the other 5

You might be better off with a slightly thicker oil for the miles on your engine - something along the lines of this.

This is what i've been using for years, currently on my 2004 180k mile a4 1.9tdi & 80k mile A3 2.0tdi
It's cheap enough through ebay sellers, proper spec & what the exact oil I used to buy from the Local VW dealership

Well done you've suggested an oil that will destroy his cam lobes and big ends !

5w40
5w30 causes lobe and lifter wear in the long run on the PD engines

I only use 5w40 made by Motul or LiquiMoly.

You are not seriously considering 5W30 507.00 Vs 5W40 505.01........ ?

Brand is unimportant , manufacture spec more so .

I think you'll find 5w40 is actually a good choice!

 

[Gazwould]

OMG you know nothing , your recommendation wasn't even a PD oil !

Viscosity does not dictate protection it's oil quality / film strength , basically first and foremost oil basestock groups and additive package .


Might as use 20W50....

VW 502.00 505.00

Vs 504.00 507.00

As stated above, go with the spec of oil.
With my old pd130 golf asz engine I used quantum platinum pd oil which is 5w 40 505 01 spec. but not longlife. (Changed yearly/8-10k miles)
In my similar engine A4 (avf) I've always used the longlife 3 which is 5w 30 507 00 spec, also changed yearly.

You'll be fine with either as long as you stick with the spec 507 00 or the 505 01 but for the money you may as well go 507 00.

Absolutely .
