I 'still' worry about the few seconds of sounds of 'dry start' each cranking after sitting for even a few hours...


One poster above mentioned a check valve, don't think there is one, as instructions for oil change mention letting filter drain into sump....

Re: Cold Startup oil flow

could be, I just figured if it was upside down and drained back, they wouldn't want to refill it on every startup. That was just a guess, anyone know for sure?

Re: Cold Startup oil flow

Talk about cringing.....There is a cautionary tale that goes with this. I usually do the oil changes myself and I'm very careful about spills. When I got back from the dealer about 4 miles away, I smelled oil fumes. Upon opening the hood I was horrified to see oil all over everything. It even had soaked some of the foam under the engine cover. Nothing was leaking at that point, it looked like the tech had not installed the filter correctly the first time and had a major spray before he saw it and tried to mop it up. Not long enough to do any damage, just make a real mess. XjoshXX was not exaggerating the capacity of that oil pump! The dealer was equally upset. They said come right back and they made good by meticulously cleaning everything including taking off the bottom skid plates. They also gave me a new engine cover off a car on the lot. They redid the oil and filter change too just to make sure. When they realized that I had been in the business, they let me work with the second tech to get it right. I believe that the first tech lost his job,even though I advocated for him. They said that it was not because of the mistake, but because he didn't tell anyone, let the vehicle out like that and gave the service manager some crap when they called him on it. Seems to me that it was a considerable fire hazard. Anyway, it's fine now, running great. If you can do it yourself, do it because you never know who is going to be under that hood. You can bet if I go back there, I'll be asking for that second tech.

I did an oil change on my 98 pickup once, maybe 7 years ago, I drained the oil, changed the filter, greased it, go out cleaned up then start the truck. I waited for the pressure to come up then realized I never put oil in it. I still have the truck and it never caused an issue.

Re: Cold Startup oil flow

Think of lubrication like hydroplaning. If you are going too fast in the rain you hydroplane. Slowing down allows your tires to contact the road again. Same goes for oil film on cams, gears, bearings, etc. What oil film is left may be thin but the higher speeds actually decrease metal to metal contact.
Speaking of oil film, don't worry about how long the car sits. Every year my race bike sits from November to March. Even after 5 months there is enough oil on the valve train to coat the feeler gauges when I do a valve lash check. There is plenty of oil still on it!

Evolv0 is just really nice
Re: Cold Startup oil flow

yeah I always wait till the RPM's drop below 1k before putting it in gear, no matter on a cold start or not. I also switched to synthetic to alleviate additional start up ware.
