I have read a lot of good reveiws on this oil and would use it in my Infinity but am paranoid about using it in my high performance sports cars . It’s said to even clean the typical yellow varnishing back to bare metal . For older sludged up cars it’s been said to change the filter in a thousand miles because of the removed contaminants build up there . Also it may take 4 changes ( typically at only a few thousand miles between) to have full effect .
I use Valvoline 5W-40 Full Synthetic in my 575M. Great oil, but I would not want an extra high detergent oil like the one you listed in there.
Unlike the old days well serviced cars these days just do not have the internal build up that can become detrimental. I agree with Terry. I see no upside.
Is the conventional wisdom still to use Valvoline 20/50 Racing as it contains the Zn additive ZDDP for the older cars that do not have a catalytic converters. Older Cars = Daytona and before.
ZDDP was an additive for flat tappet cams. 275 4 cam, Daytona, Dino and C4 were the start of that for Ferrari. Daytona, Dino and C4 were known for cam wear issues. If I owned one I'd use it. Earlier cars had no issues that additive would apply to and later cars have not ever had a cam wear issue, Ferrari got it figured out. .
Good quality synthetic oils do this anyways in normal use. I've never felt the need for specific "cleaning" or "high mileage" oils. I think they can do more harm than good.
I am not sure what harm they can do, all the oils meet the manufacturer specifications I would think.
If you really want to clean the engine, just use some fully synthetic truck oils :do come with lots of detergent, and with or without ZDDP (regular / low saps). A more expensive approach is to use ester oil (ex: Motul 300v) : these oils tend to dislodge all the crude. They will definitively remove the yellowish varnish. On a very dirty engine I prefer to use cheap dyno oil and new filter, that I replace shortly after. This is less aggressive, so less probability do dislodge a huge chunk that can clog the oil system. But as others have said, any car that has been serviced regularly should not exhibit significant build-up.
Most "high mileage oils" have additives that are intended to swell oil seals - supposedly to cut down on leaks, as well as some aggressive detergents. I am not sure I trust those additives long-term in a high performance engine. While the Valvoline Restore & Protect doesn't specifically say it's a high mileage oil, It seems like that is part of the market they are trying to capture, so I suspect some of these types of additves are used. I am positive it's not a "bad" oil but it wouldn't be one I would pick for a Ferrari application.
I use Mobil 1 synthetic. I’ve pulled rocker covers off two of my cars with over 150,000 miles. There was no build up what so ever.
All modern oils have detergent properties that keep any contaminants in suspension until the next oil change. Unless you’re starting with a junk yard engine, there is no need to use a specialty oil.
