I switched AMSOIL last winter. And I change to regular oil in spring. I got oil leak on same day. I tighten oil pan gasket again. No leaks So far.
I want to change to AMSOIL again. Can I expect oil leak again?
car was olds 88 year 94 mile 155K

If you have run Synthetic oil ONLY in your car or truck for more than 100000 miles and developed a oil leak let me know by # 1. If you have driven your car or truck more than 100000 miles on petroleum oil ONLY and have developed a oil leak let me know by # 2. If the answer is NO to #1 then answer #3.If the answer to #2 is NO then answer #4. The outcome will be fun.
1990-1992 1/2. Suzuki Sidekick 2-door, 8-valve SOHC 1.6. #4.
1994-1998. Ford Bronco 351 v-8. 150,000 mi. #4.
1994-1999. Ford T-bird v-6. 175,000 mi. #4.
1999-2004. Suzuki Sidekick sport 1.8L 16-valve. Short on mileage, only 47,000 now. But no leaks on 100% dino diet for 5 1/2 years.
Mulitple cars. Some 1, some 2. They all leak eventually no matter what they are or what you run in them...
1, 1, 1, and two cars with less than 100k miles where a leak developed within 5k miles of switching to synthetic (redline in one case, GC in the other).
EDIT: sorry, the 2 last cases weren't switching from petroleum to synth, i meant to say switching from M1 to redline and GC.

(Qualified: switched to synthetic at about 110,000 miles, now at 255,000, so that's over 140,000 miles on synthetic (Red Line). Comments: had minor seepage from oil pan gasket before switch and had already replaced both main oil seals. All were changed later. After head gasket failure at 240K miles, valve stem and camshaft oil seals were replaced while head was off. Car uses/loses no oil.)

multiple cars:
4, 4, and 2
how many entries are needed to tabulate the results?
will p value be calculated?
