Not really enough room in our engine bay for this…

 

According to their own blurb, see here for example https://www.valvolineglobal.com/en-a...e-and-protect/, all this "restore and protect" effects is the pistons.
Trouble is the main problem with GDI is carbon build up on the backs of the intake valves and in the inlet ports, and of course you don't want oil getting into those areas. I have not read or heard of carbon build up on the pistons being a problem in the AJ126 or AJ133. So I don't see how this new brew achieves much if anything over the use of premium fuel and/or fuel additives, at most it keeps the sides of the pistons and particularly the rings a little cleaner.
All that said I have used Valvoline 0W-20 ILSAC GF-6A for the last two or three oil changes anyway!

 

Great point and agree. Short version, it seems like a very good oil.

At least the Valvoline engineer took this question on directly:
at around 12:00....he hedges a bit and confirms your point but notes it might help on the valves.

It probably cannot hurt things.....if the cleaning fluid gets aerosolized and helps, so be it. I wish JLR had done a Toyota thing and had both injection systems....that being said, the AJ126 and AJ133 are not known for big carbon buildup for whatever reason where the Audi cars were (forget the models but the RS4 was notoriously bad....possibly the 2.0T).

Video is interesting....it is a company person but he seems legit.

I want to repeat this: I have nothing to do with the company or oil, don't sell oil, and do my own changes with a mightyvac in my garage like many. Cars have a finite life and I have finite money- so am trying to optimize things in that context.

 

Thanks for the vid, I had not thought about the major contribution of the PCV system to carbon build up on the inlet valves etc and maybe just maybe this new oil might reduce some of that although I am not sure how that might work. Pity he says PVC every time though which might confuse some of the punters!

 

Agree...for a while I was obsessed on NOACK scores and then realized that a difference of say 7% to 10% probably in terms of the PCV meant not much....plan to check my filter often....have 3 or 4 of them in the garage on a shelf.

 

Yes Ford went to dual injection on the 2018+ 5.0L Coyote engines. But they said it was for increased power and efficiency and no mention of reducing the intake valve build up?
I guess it helped?

I just use the Penzoil Ultra Platinum that you can get at Walmart for $29 for five quarts. Between all the various "premium" oils available from the various vendors, I doubt the minor variances between brands makes ANY meaningful difference, at all, in engine longevity.

 

Use a fuel additive to keep the injectors clean.

 

On a GDI engine, that only works on the INSIDE of the injectors. (Not that this is a bad thing)

 

Have you ever looked at that tiny hole the fuel squirts out of ?

 

Same here.

 

I use the Redline Complete Fuel System cleaner about every 3-4 tanks. Also run it through the 2013 Golf and 2022 Silverado.

 

Are you referring to Redline S1?

 

I see S1 in the title, if that's what you are asking. This is the stuff, perhaps not the exact vendor.

 

Yeah, thanks for clarifying. That’s the stuff I use as well. I would probably try the BG44K stuff that everyone recommends but for some reason it doesn’t seem to be as readily available in Canada. You can get it on Amazon from the people trying to take advantage at double and triple the price (or more), but not for what it should be at.

 

This is ALL I use now. Basically it is an upgraded JLR spec with better timing chain wear protection. Love Liqui Moly and this oil.

 

No injector cleaner/Fuel additive is going to help with the carbon build up on the valves....Because the GDI injector sprays directly into the cylinders and no fuel hits the back of the valves like with Port Injection...Thus the issue. You need to use a fogging cleaner through the intake to get to the backs of the valves. Just FYI.

Another benefit of my Water/Methanol injection, is my valves get a nice hot Alcohol steam/mist bath every time it sprays. You can use a PEA cleaner like this also to clean the valves pretty easily.

Interesting - saya to spray it into the throttle body, our cars have a supercharger and intercooler in the way, think it will remain effective?

 

It goes into a vacuum line, not the intake. The vacuum pulls it in and then you let it soak before driving again. Most have pretty good instructions with them.

LIqui Moly's label states that it meets the spec STJLR.03.5006, so I don't understand your apparent rejection of it, in favor of Castrol. Am I missing something?
