Let's talk crankcase oil capacity once again. Many years ago, I started a thread about this topic because my oil tube and dipstick were destroyed by the shop that installed the headers. The new fill line was not calibrated to the oil pan, and they never marked the stick at that current oil level. Eventually, it got marked at the 5 qt. level, and I've been running it like that for years. Recently, I had the oil changed and I was perusing the owner's manual which states that the 454 uses 7 qts. I believe this is minimum, as other features such as coolers, filters et cetera will require more oil. Does anyone use less than 7 qts. in their 454? Or should there be a minimum of 7 qts. in there at all times? Thanks.
Here is the original short thread.
