Title: 5w 40 fully synthetic oil..
Post by: jimmy-s3 on January 04, 2015, 10:16:24 pm
Would there be any reason why you couldn't use 5w40 fully synthetic oil in an Edition30?

A lot of people including myself move to 5W40 fully synthetic oil once running higher power levels. No reason not to use it.

Full synthetic will withstand higher operating temperatures in the engine itself for longer, and opting for 5w-40 over 5w-30 further aids this. I've also made the switch to 5w-40 fully synthetic oil.

VW 504/507 approved oil is one grade only, 5w30.
5w40 is thicker at temperature, by how much I have no idea.

Make up your own mind.

Depends on the oil, if you look at the datasheets they give the viscosity at a given temperature. Quantum 5w40 is only marginally thicker than Castrol 5w30 at 100 degrees from memory

I was lead to believe that although 5w-40 isn't VW spec, when running any level of tune the excess heat generated in the engine is controlled by the thicker oil. Certainly my engine feels smoother when running it through the upper rev range at temperature.

@ROH ECHT (http://www.mk5golfgti.co.uk/forum/index.php?action=profile;u=3794) might be for the warmer climate?

What @MC71 (http://www.mk5golfgti.co.uk/forum/index.php?action=profile;u=4913) posted is the stuff you need.

I'm good...thanks  :happy2:
Some here use 0w40 or even 0w30 in the colder states...but most here use 0w40 or 5w40.
If it is VW 502.00 and 505.00 coded.

5w30 is fine and is the VW spec but if you drive quite hard and especially if your engines tuned it sees very high temps. At higher temps the 5w40 lubricates better than the 5w30.

This....


is what i have


oil temps dropped from about 95-99 on the normal 5w30 oil to 85-90 on the millers stuff. also it doesn't heat up as quickly and when it does, it cools down better too (unsure how really but hey ho!  :stupid:)

i have my oil temp on my fiscon on all the time so always watching it.

I was going to try it when my local specialist dropped the oil for me a couple of wks ago, they refused point blank to refill with anything other than the 5w30 castrol. Looks like it's up to me when it needs a change next time round.

Jkm in Portsmouth suggested 5w30Castrol for my car

thats exactly it and 5w30 (and more expensvive)is normally longlife schedule, i use 5w40 quantum fully syn from dealers (tps) which is castrol better for tuned engine as lubes engine better, ive herd good results about millers but im sticking with what dealer recommends !
