5W20 vs 5W30

[Loris]

Basically what is the difference?

Ive just taken possession of my new 2011 Nissan Juke with a 1.6L turbo engine.

Nissan recommends 5W30, but will Pennzoil Ultra 5W20 work safely? Once it's broken in, i'm thinking of going to synthetic at the first oil change interval of 6K.

thanks

I know the search feature on here isn't the best, but you'll be able to answer a lot of your own questions by using it.

The difference is the range of visocity at 100C

20: 5.60-9.29 cSt

30: 9.30-12.49 cSt

I'd use what Nissan recommends

I wouldn't go lighter than recommended, particularly in a turbo engine. The 5W-20 will be thinner at operating temp.

run what nissan says to run,,yes u can use synthetic at the 6k interval. amen.

5w30 And with syn oil go with the longest oil change interval recommended in the owners manual. If you do only super short trips then conventional oil at the severe oil change interval would be the best choice.

Run the factory fill to 3750 miles (i.e. Nissan's Schedule 1 interval) and then switch to the synthetic of your choice. Since Nissan recommends 5w30, stick with that.

For a Turbo....sounds like Shell Rotella T-6, fully synthetic, would be a nice fit for the Nissan.

This was just discussed try a search.

I think Mobil 1 Advanced Fuel Economy 0w30 and Castrol Edge 5W30 are pretty close to a 20 and get sheared down to a 20 as it's being used. That might work for ya.

This is what I dont understand re; my car. Toyota back speced the use of 5W-20 to 2006. And of course I have an 05. So if most 5w30`s shear down to a 20 weight anyway,what`s the difference?

My VW turbo specs 40 wt. In turbos, you need a bolder approach in regard to lubrication. Don't go lighter. If for nothing else than staying within the warranty requirements.

I wonder how GC (Castrol Syntec 0w30) would fair in this rig? Should be a good fit.

Yep, don't go thinner or thicker than what the factory reccommends. And with a turbo I'd be using one of the better synthetic 5w30s out there, and I'd idle my engine for 30 seconds before shut down. Dump the FF at 3k and then start your 6k intervals.

5w30 and 5w20 perform identically at low temperatures (hence the 5w).

The 5w30 will remain a bit thicker at high temps. This generally equates to better protection at the expense of some fuel economy and perhaps a few horsepower.

The 5w20 will stay thinner at high temps. This would offer slightly less protection but mean better fuel economy and some extra horsepower.


Best bet is to stay with what the manufacturer recommends. There are plenty of good 5w30s and 0w30s out there. GC would work great for his turbo motor.

There isn't much difference. The 20 weight oils seems to be pretty shear-stable. Using a thin 5w30 isn't much different as using most any 5W-20.

 

[dparm]

What is the specific Toyota recommendation? Is it as simple as "any 5w30" or do they require a certain API service grade? The Germans seem to love coming up with huge lists of approved oils but the Japanese have historically just said "any API SM or better" (Nissan, for example).

My guess is that they suggest 5w30 for this motor for the extra protection of the turbo. I would not deviate.

And your worried about using a 20 instead of 30 for fuel economy purposes?

This car can get almost 900kms on a $40-$45 tank CDN funds of course.

3L/100km is good enough.

 

[Alex38]

Stick with 5w30 synthetic, you have nothing to gain by going to a 20wt.

 

[Loris]

My primary concern is for the turbo - secondary would be fuel mileage as i dont think i can have both.

I mentioned the 5W20 because i happen to have a jug of the PU in 5W20. I think i will let it sit and get some 5W30 since that's what Nissan recommends.

Is the PP a good enough synthetic oil? Or has the PU proven to be better? Or another brand?

thanks

 

[barlowc]

Depending on where you purchased the jug of Pennzoil Ultra 5W-20, you might be able to exchange it for a jug of 5w30.

RE: PP being "good enough", it's way beyond that. used oil analysis have shown it to be an excellent synthetic.

 

[dparm]

Pennzoil Platinum or Pennzoil Ultra are totally fine for that car. There's definitely better oils but you'll pay more and have to order them online.
