Idk about doing that though unless I flat out confirm it.Hello everyone, how was your day? I’m coming back with a new topic about the Chevrolet LS1 5.7 Specs and Reliability. It calls for 0w20 but I've also seen a few people say that Honda is, in some places, recommending running 0w16 to get it up to operating temperature even faster. Out of curiosity, what oil would you guys suggest? I've read that the reason direct injected motors use such thin oil is because it allows the engine to reach operating temperature faster. Also it's going to be garaged all winter because I wouldn't drive a car in Michigan, in the snow so cold weather isn't a concern. Then I drive it easily, short shifting until operating temperature. ![]() What I've been doing is starting it and waiting for it to idle down when it enters the "closed loop," which I have to look up again because I forgot what that even means. Also excessive idling and excessive engine breaking. I read that in these engines, some of the conditions in which oil dilution is encouraged are cold starts and driving before reaching operating temperature. It takes so little oil that there's no reason to ever cheap out on it, which I don't even do in my trucks anyway. I plan on changing the oil at 30-40% life just to keep it extra fresh and using whatever the best oil my research tells me. I had basically already planned on doing what you're suggesting in a few ways. There is actually a bunch of legitimate, peer reviewed literature on this topic if you search for it on Google scholar. I eventually found out that this was a concern in all direct injection motors and decided to put my faith in Honda a little bit. Initially when I heard about the oil dilution in the L15B7 I told myself I wasn't going to buy the car. That is something that I was also going to ask about but in a different post. This will assist with flow of the drain and allow it to peel from the frictional surfaces. This way, you allow the additives manufactured into the oil do absorb as much carbon based elements in their surroundings. I always suggest using Synthetics that have the highest content of Detergents & Dispersants. The Synthetic will be far less likely to ACIDIFY & OXIDIZE on metal. What I am suggesting is that if you use a Synthetic Oil (in of itself) you will decrease the Carbon Footprint in the Engine as opposed to using a non-synthetic oil (which are highly Carbon based). The blow-by that does find it's way through that path is now more than just a carbon based break down, it is layered with hydrocarbon distillates which together decrease the chance of adhering to the valves. That fuel in the oil is actually "complimenting" the disformation of carbon making its way out of the combustion chamber, around through the air intake, then back through the intake manifold. However, keep in mind what many compain about: Oil Dilution. Over time it will build and build and "cake" on (sort of speak). ![]() Mind you, that without a port injection setup spraying over the valves, eventually they will get covering in carbon based particulates. This has really come into place about 4years ago (after the manufacturing) and the focus has been on the PCV systems. More modern manufacturing has taken precautions and improved the secondary effects of "blow-by" in direct injection platforms (especially turbo charged engines). If it had (2) Set of injectors, then it would be a Multi-Port. There is only (1) Set of injectors - thus, DI platform. So the question is, does the L15B7 1.5T in the newer civics actually have that second set of injectors in the ports or is what I read false? I've been unable to confirm it. I'm probably still going to get an oil catch can because it just feels better to know I'm keeping that gunk out, but I still would like to confirm whether or not thats true about the set of secondary injectors. I also read in one place that the reason it's not a huge deal on these motors is because there's actually 2 injectors per cylinder, one that injects directly and a secondary injector in the port where it normally would be. I've read that in the newer Honda gdi's this isn't as much as a problem. It's pretty easy to understand why port injection keeps the valves clean by spraying gas on their backsides and how injecting directly into the cylinder means they don't get the same cleaning. ![]() One of the things I stumbled across was about direct injection in general and has to do with carbon buildup on the valves. I bought a 2018 civic si as a daily driver and have been doing a fair bit of research into the L15B7 motor. I have a LOT to learn so I'm sorry if this is a dumb or previously answered question. I'm fairly new to the car scene and have a quick question about direct injection engines.
