Best 5W-40 or 0W-40 For DI Noise?

[Patman]

I never worry too much about how the valve train in my engines sound as I always have the metal cranked up

Gotta say, I think the industry really dropped the ball, or jumped the gun too early on this GDI. Wish they found that 0.2 MPG a different way. (That ticking in my Tacoma makes me fell so ghetto)

Unfortunately consumers end up being the guinea pigs because any new technology in a couple cars gets spread to every car on the market within a few years. DI, VVT, turbos, transmissions with a whole bunch of gears. We went from 6 to 8 to 10 speed faster than we went from 4 to 6 speed. I miss quiet engines, it was an easy quick way to tell if a car was maintained. If your engine made noise it meant you didn't do your oil changes.

Colorado v6 is noisy especially when cold. Quiets down once warmed up. Not sure any oil would make a difference. RL is one that comes to mind that anecdotally appears to help quiet some valvetrains.

I believe we have the same 3.6. Mine also quiets down when it's warm but still very noticeable in a drive thru or when being around the car when its running. RL does seem to help quiet a lot of Ram and other noisy valvetrains. It quieted mine as well but not enough to make me want to more than double my oil change budget. I'm sure I can find a $30/jug alternative on the shelf at Walmart that quiets the ticking.

2012 is a different motor (LGZ 2017>) but likely similar noise you're hearing. Maybe try a 5w40 like QS Euro?

My Benz M276.8 engines are notorious for loud DI noise and valvetrain/timing noise.

My experience:

M1 0w40 was VERY noisy.
Castrol 5w40 is much less noisy (compared to M1)
Mobil Racing 15w50: quiet as the grave.

Obviously MR 15w50 is not really suitable for long drain interval, all season use (if you have cold starts and low winter temps).

So I've run Castrol Euro 5w40 for the last few years, no complaints.

same goes with Toyota D4D engines, M1 5w-50 works for me the best over all other oil i have tested. When it comes to reducing valvetrain and di noise

How does it stack up to M1 ESP or 5W40/0W40 M1 FS?

I think those M1 oils are better in a DI motor but have always been louder in my cars. PUP also runs quiet in comparison.

Yes my 3.5's have a lot of ticking from the injectors. Not so much from the lifters. One has HPL Euro 5-40 and the other QS Euro 5-40.

11th hour curve ball. Liquimoly Ceratec.

 

[TwoC400s]

11th hour curve ball. Liquimoly Ceratec.

I tried the full LM additive kit from FCP Euro in both cars 2 years ago. Made no change to the HPFP/Timing noise.

It probably wouldn't help with DI noise, but I've found the HPL Euro 5w40 pretty smooth (probably thanks to the Moly).

If you were ok with only a 5w30, Restore and Protect is pretty quiet/smooth too (in general not necessarily for your situation/engine).

 

[Accent Abuser]

DI does more than save some fuel.

Yup, no way would we be getting the power AND the fuel economy without DI. Running 87 octane gas with an 11-14:1 compression ratio and not burning a hole through a ring land is only possible with direct injection.

I wouldn't mind trying HPL but I think I'm going to stick to non boutique oils for now. I wish VRP came in more viscosity options because it seems to be some stout oil. I don't think I need any cleaning but if VRP can clean deposits it should have no issue preventing them to begin with which makes it a good oil in my eyes. It will be interesting as time goes on to see how effective the "Protect" is in VRP. We know it can Restore.
