Overall, the SYPRIN Original Engine Flush is a great choice that’s been tested and proven to work on a wide range of engines. Simply pour it in, wait between 10 to 15 minutes and then replace with fresh oil. Forté Oil System Protector has been specifically formulated to prevent the effects of contamination build-up and crankcase acids within the engine oil system. Extended oil drain periods and stop/start driving conditions place greater demand on engine oils to provide suitable protection on technically sophisticated engines, compromising the engine oil’s ability to protect and leading to excessive wear and reduced engine efficiency.

I would be wary of fuel system cleaners - where are they moving the crud to? I would be happier for it to stay in the low tech, cheap parts of my fuel system rather than clog my injectors, thanks all the same!Forté Petrol Specialist Injector Cleaner is compatible with all fuel system and engine components, including lambda sensors and catalytic converters. I have just had my Barchetta serviced, part of which was to have Forte Flush additive put in prior to the service. I am a little worried that it was in the engine for too long. Forté Advanced Formula Motor Flush is fully compatible with all engine components and engine oils which are formulated to meet API and ACEA Service Classifications and international motor manufacturers' specifications. Having been given a jar of Forte's "Advanced" diesel treatment and quite willing to try it and see what happens I would still be interested to hear the views of anyone who has actually used it and come to a conclusion one way or another.

Wynn’s are a reputable brand known for their fuel injector cleaners but they also produce a variety of other cleaning additives such as their engine flush. Unlike some of the alternatives that are suitable for just engines, this particular formula can also be used for hydraulic systems, gearboxes and even differentials. Speaking to some other people they said its fine to run it with the engine flush in, for a day or so before draining and results are better, I have no issues with this, but I have also heard that FORTE ADVANCED FORMULA ENGINE FLUSH is a well respected flush. I've got a feeling this Forte stuff was on the invoice after the Renault's service (at a main dealer) If the flush is only supposed to be in the car fro a short time, I certainly was not advised of this by the garage. Forté Diesel Particulate Filter Cleaner and Regenerator has been specifically formulated to combat the adverse effects that start/stop driving conditions have on Diesel Particulate Filter (DPF) regeneration. With a continued stop/start driving patterns and road restriction challenges such as regular travel in low speed zones, soot loading builds up in the DPF since the ECU is unable to make the necessary small adjustments to the fuel injection timing to increase the exhaust temperature and initiate regeneration.

Can also be used for regular maintenance in conjunction with Forté Advanced Formula Diesel Treatment. If you really want to flush the engine, go and buy your chosen oil and filter, plus 5 litres of cheap oil that meets the minimum spec for your engine, and a second filter. Change the oil for the cheap stuff, change the filter and take the car for a long drive. Get home, drop this cheap oil straight out, replace the filter, and refill with the good stuff.

Forté Petrol Specialist Injector Cleaner is a complex blend of specially selected cleaning agents which act together to dissolve deposits that are formed in fuel systems which restrict the efficient delivery of fuel to the combustion chambers, this is also key to reducing the risk of the LSPI phenomenon by keeping systems pristine. I have tested cleaners out over a period of years including rolling road test to see what achievements could be obtained, I have been to fuel/oil research laboritries & seen fuels & oils tested on engines running flat out on dynamometers. The caveat here is i do mainly cheap ass cars that are not worth doing a top end rebuild on so the s t or bust option is often the way to go for my customers BUT it does what it eays on the tin, wether that leads to other problems are totaly vehical and condition specific, it' a tool and you need the experiance as to how and when to use it or not, people who continue to call it snake oil are simply wronge or have no real insight into how and when to use it. Forté Advanced Formula Motor Flush is fully compatible with all engine components and engine oils which are formulated to meet API and ACEA Service Classifications and international motor manufacturers’ specifications. Toyota Land Cruiser KDJ125R (SWB) 3.0cc (1KDFTV) Turbo Diesel (D4D) RHD (52 - 09 reg, 9/2002-12/2009) PradoThe real danger of using engine flushes could be when they are used in high-mileage cars. For cars that have already had a long lifespan, the engine seals may be worn and leaking. In these cases, the combination of oil and sludge is almost acting as a sealant, essentially keeping them viable and masking their true condition. It is formulated to overcome the increased levels of contamination in modern high output tight tolerance engines caused by the effects of biodiesel and ethanol based fuels and exhaust gas after-systems. I don't think many people contributing to this forum have carried out enough research to tell you if some gloop in a tin works or not. I suspect not even HJ actually runs an engine testing lab, but if he has some serious statistically valid data, then I (doubtlessly among many!) would be interested to see them. Forté Petrol Specialist Injector Cleaner should be used at regular service intervals or whenever symptoms indicate that treatment is necessary.
