I use the Crc Gdi Intake Spray, Gumout Multitune 1 Oz per qt in oil and drive for 10 minutes to dealership for oil change, rest in fuel tank; it has pea in it as does the crc spray.Which specifically - if you know or can share?
EFI should have been left alone, it worked fine.
The 2.0L Ecoboost is actually efficient enough that, going down a hill with no throttle input at interstate speeds, coolant temp will drop at least 20-30 degrees. Highway miles tend to be very easy on it, even in 90-100mph traffic for 30-40 miles on end.I wonder if this is part of it? Theorizing? I think a lot of engines never get hot enough.
You would be surprised how often this works, especially on diesels with variable geometry turbos.VW even recommends an "Italian" tune up (15 to 20 minutes) at 3000 RPM (have to use a gear or 2 lower than the highest) to burn away deposits.
did they get rid of that for the new model years?Yes, thats the MPI + GDI. Its not just for that however. MPI is more efficient at idle and low RPM. It also allows them to size the GDI injectors better for load. I have a Toyota Dynamic Force 2.5l Rav4, and the gas mileage for a vehicle its size is very good IMHO - 29 overall mixed use city and highway, 35 ish on highway if I keep it under 75 - my calculations, not a computer.
you drive alot?, is the vehicle you are talking about the 6.7td?240k on mine, 10k OCIs, no catch can, and I don't run top-tier fuel. Weird how I don't have any of the problems that anti-DI proponents constantly crow about. Weird. Idle is dead solid stable, oil analysis comes back great at 10k, doesn't burn oil, 31mpg on long interstate trips. It even has a horrible, terrible turbo to make things even worse.
I guess I must be the exception to the rule. According to the Youtube experts, my engine should be so full of carbon right now that it shouldn't even be able to physically turn over, let alone run.
A minimum of 100 miles a day (commute), but this is in the 2014 Fusion (2.0L turbo DI). The cinder block of a diesel only sees maybe 5,000 a year, if that.you drive alot?, is the vehicle you are talking about the 6.7td?
How long have you been doing that please ( driving with 1 once Gumout Multi tune in the crankcase ) because I was thinking of trying that myself.I use the Crc Gdi Intake Spray, Gumout Multitune 1 Oz per qt in oil and drive for 10 minutes to dealership for oil change, rest in fuel tank; it has pea in it as does the crc spray.
there is the answer on why you have no issue, you drive a lot, Italian tune up not needed for you, but for most they drive 10% of that.A minimum of 100 miles a day (commute), but this is in the 2014 Fusion (2.0L turbo DI). The cinder block of a diesel only sees maybe 5,000 a year, if that.
No. It is one of the reasons I prefer Toyotas actually.did they get rid of that for the new model years?
That was the reason I bought a Pentastar.As you mentioned there were other improvements along the way. My bet is the numbers might be a little closer with those improvements minus the DI. The 3.6L Pentastar makes HP 305 HP in the RAM 1500 w/o DI. My bet is similar HP and mpg for your 2023 example.
The problems are lazy, broke vehicle owners who won't do the necessary maintenance and won't take unpopular steps to reduce the carbon / soot buildup.
Mid/premium fuel, 12k intake spray cleanings, shortened OCIs and Dexos 1 Gen 3 oils are just 4 of numerous, unpopular ways to help keep the engines cleaner.
Do a Google Search on this subject and find more ways. But if you just want to look at your GDI / TGDI outside in the backyard and continue to sit on your hands, then expect conditions to worsen over time.
The dynamic force 2.5 (Rav4 and Camry) has had it since the new design. The 2.0 in the Corrolla Cross has it. I am unsure which other models have or are getting it - but there clearly moving this direction, not away from it.did they get rid of that for the new model years?
I don't go over 20 miles, all highway keeping rpm below 4kHow long have you been doing that please ( driving with 1 once Gumout Multi tune in the crankcase ) because I was thinking of trying that myself.
Don't those have an oil bath timing belt?I was nervouse about purchasing my 2021 escape with a GDI turbo 3 cylinder engine. It is my work vehicle delivering medicine for a major hospital in the area. I change oil every 5,000 miles....just recently changed to Amsoil XL and doing 8,000 mile oci. So far so good at 190,000 miles. Runs absolutely beautiful and hoping it continues....many miles of all freeway driving daily. So far been very happy except for my transmission going out at 100,000 miles.
High octane fuel does nothing unless the compression ratio of the engine requires it. Running high octane in a low compression engine is actually ungood, since the fuel doesn't burn completely (octane being the resistance of fuel to compressive detonation) and leaves deposits behind. DI/TDI engines are normally high compression enough to need high octane, but not always.Why or how does higher octane fuel help? We are doing top tier 87 in our new pathfinder
