anyone using 5w40 instead of 5w30 on tuned cars ?

[byebyeSTI]

ive been using motul 5w30 since new on my 3.3 , im adding a jb4 and some other bits

some tuners have recommended using the 5w40 instead i have run it on most of my European cars and had good luck

Unless engine temps were higher due to mods (and i do not think they are), you do not need a thicker oil. Running a thicker (higher number=resistance to flow) can only reduce performance and perhaps even slightly hinder the oil system (oil pump has to work harder to push thicker oil). So, I would stick with OEM recommendations.

I use mutol 5w-40. Im tuned 2.5 lap3 ecu, wmi with e30. Been using since my second oil chang on my car never looked back. Never had any issues. With 5w-30 non tuned with e30 I would burn oil either seeping oil from turbos or burn on rings. But now that I’m tuned and run thicker everything good.

i think 5w40 is fine its not that much thicker than the 5w30 and offers better shear strength at high heat levels , i think its also in the oem service manual for severe service oil .

When I get an oil change my mechanic uses 5W-40. Liqui Moly to be specific. Been using it ever since my second oil change and have had absolutely zero issues.

It’s recommended by the lap3 rep to use 5w40 when tuning the stingers and especially with ecu & full exhaust/ or downpipes. Helps in reducing the amount of oil seeping. Next time I change the oil when it gets warmer I’m going with 5w40 as I have 5w30 right now.

several weights are fine as long as you meet the temperature range of hapiness .

Note: that chart is for 2018 MY, IIRC. The 2019 manual leaves the 2.0T the same, but reduces the 3.3TT to 10w-30 and 5w30. Which has led to a bit of confusion. There was a bigger oil thread before where this was discussed in more detail.

I would have to agree that since I have used Motul 5w-40 for the past two oil changes the level on the dip stick hasn't moved. I check my oil every week or two. So oil consumption is little to none compared to when I was using 5w-30. When using 5w-30 the oil level would slowly creep down the dip stick throughout the oils life cycle. It would be nice if I could find a 5w-40 that meets API SP or ILSAC GF-6A standards. One thing about Motul 5w-40 is that it is high in calcium which has been known to promote LSPI. So I'm still searching for the best oil for my Stinger.

nice share the results if you find some

I use liqui-moly 5w-40

I use Liqui Moly 5W-40 and meets API SP. Have had no issues what so ever. This is the product name Liqui Moly Leichtlauf High Tech SAE 5W-40.

Prime example why I shouldn’t be multitasking at work lmao. Mixed the N with a P. But anyway probably gonna be a hard find for API SP. But we are going to see if the other user finds one.

i have like 10 oil dealers here at work not one with those specs in 5/40 .. im using the x-cess 5/40 gen 2 from motul im happy so far and i do 3k oil changes so im sure its fine

Through oil analysis is how I found that Motul is high in calcium which has been shown to promote LSPI. You can see in the oil analysis Motul is loaded with calcium compared to all the other oils I have tried. This is why I won't continue to use Motul. I might give AMS oil 5W-40 a try or I might just go back to AMS oil 5W-30 signature series. Since AMS oil 5W-30 was my best oil report so far. AMS oil is the column to the right of my unit averages and Motul is the column to the left of my unit averages. I want a 5w-40 oil that meets API SP standards but I doubt there is one out there.

Shell Helix Ultra is MB 229.5 BMW LL01 and also API SP made from GTL base.

I use motul 5w-40 and now you have me thinking of switching it up. How late in the game in the cars life do you think the high calcium could actually affect the car?

I wish you was right my friend. I went to the Shell website and checked it out. Says API SN per Shell's website. Unless I looked wrong.

Redirect Notice

Here is an article that talks about LSPI with relationship to higher levels of calcium in oil. Best case scenario nothing happens. Worst case scenario you get a cracked piston. The likely hood of it actually happening is probably low but since I'm tuned (running higher levels of boost) I want to take every precaution I can

As far as I know, lspi only happens if you lug the engine (I.e floor it in 7th at 1500 rpm in manual mode type thing) - l stands for low. I don't do that. My racing shop mechanic recommends motul sport 5w40 for the track due to higher temperature stability. Not 100% saying he's the absolute expert either.

I asked some questions on bitog and the suggested m1, which my mechanic hates and was terrible in my subaru. Quaker state full synthetic 5w40 euro has a40 and mb 229.5 qualifications and lower calcium, iirc, and so does Castrol edge 5w40 euro - but they're hard to find..
