TR6 TR6 takes 6 quarts of oil?

Okay, what am I missing? I thought it was 4.5 quarts. I have what looks like the original dipstick, and was quite surprised to see that 4.5 quarts barely took it to the minimum level. Six filled it perfectly. I must be missing something very obvious.
 
Thanks, Roman. That's interesting. I could swear I've seen recommendations from Americans that it takes 4.5 quarts. Maybe they were referring to the Brit quart? Anyway, I was starting to think maybe the p.o. had used a larger oil pan. All of the illustrations in the parts books shows the drain plug on the side of the pan, but mine is front center. I was grasping at straws, I guess. Anyway, thanks again for the help, Roman.
 
When I was in high school I worked at a Jiffy Lube. The standard for filling engines with oil at the time was this. 4-cyl=4qts., 6-cyl=4.5qts and 8-cyl=5qts. This was considered minimum to start the engine and check for leaks after oil pressure came up. Then we checked the dipstick and topped up accordingly. That might be what whoever was going by when they told you.

My '72 took 5 until I added an oil cooler. Now it takes 6 quarts. My drain plug is also in the front center of the oil pan. Someone on the 6-pack mailing list took a poll on front or side drain plugs. Evidently both were very common.

I don't know squat about TR6s, but I had a somewhat similar problem with my old TR3. I would check the oil and it would show fine. Had a bearing nocking for a while so I cranked it only enough to keep the engine free and lubed up. Finally got around to checking everything out and realized the little stop on the dip stick wasn't in the correct place. Thus, when I was sticking the engine, the dip stick was going into the sump too deep and I was driving around with too little oil. So that's why I had low oil pressure! I'm amazed I didn't kill that engine.
