Switched from 0W-30 to 0W-40 oil

**Martin** · 17-10-2013, 02:14 PM

On my last oil change I changed from using 0W-30 oil to 0W-40
I've done 2,500km since then, so far so good...
The engine is a little bit quieter, the oil consumption is a little lower

I am trialing a similar thing on my mates MK5 GTI. I am his resident mechanic, so i do all the oil changes etc and basic maintenance. We have used various 5w-30 VW approved oils - from Shell Helix Ultra Extra, Castrol Edge (not VW approved actually) and more recently Penrite Enviro+.

Regardless of oil brand used, the car drinks about 500-600ml per 1,000km and therefore goes through several litres of oil between each service (services done at 10k intervals because he couldnt care less) which is annoying.

Did a service on his car about a month ago and decided to try Penrite Enviro+ in a 5w-40 weight. So this oil is a little bit thicker when hot. The 5w-40 is actually about $20 cheaper than the 5w-30 so if it works out to reduce the oil consumption then its a win win situation.

I assume it is still 504.00 spec?

Nope, it isn't.

Ah yeah, it's actually 5W-40

It's 502/505 spec

Although VW 502.00/505.00 or VW 502.00/505.00/505.01 lubricants are acceptable to use on vehicles with fixed service intervals without a DPF, I believe that it's better to use VW 504.00/507.00 lubricants in direct-injection engines, as the following link will demonstrate:

ACEA Conference Papers - The Lubrizol Corporation

Download the conference paper titled, "Lower SAPS Engine Oils - Essential components in maintaining vehicle emissions compliance", dated October 2006, and head to page 19 & 20.

In direct-injection engines, fuel is injected directly into the combustion chamber, which bypasses the inlet valves and is unable to clean them. Using a low-SAPS or mid-SAPS engine oil may reduce the rate of deposit formation on the inlet valves (or so the theory goes).

Penrite state that 5w-40 is a low/mid SAPS oil and is designed for use in modern direct injection engines.
Looks much the same stuff as the Enviro+ 5W-30 which is 504/507

Lucas, my TSI engine was drinking 750ml per 1000km and that's now down to about 500ml per 1000km (maybe/approx)

You could also try Mobil1 5W50

That could be awesome for a little more protection on hot track days - thanks!

My 09 vRS has never used a drop between oil changes. I believe the cost for VW 504/507 approval from VAG is about $650 K for 3 years. Nice money earner for VW just to put a stamp on your bottle. I m sure plenty more oils meet the criteria but refuse to be blackmailed.
