I was kind of thinking it would be fine, I just mentioned the new car because I used 80-90 non synthetic, and it didn't shift real well, I put the 75-90 synthetic in and it worked flawlessly. There is simply no way to utilize the squirt bottle to fill the new car, the hole is simply buried. I change the oil often enough I want a real genuine industrial oil pump, I have about 6 of those cheap little plastic pumps all broken to some extent or another, I swap parts around till I get one to work. One of them didn't even get one stroke, I pushed it down and the bottom blew off. Right out of the box. I'm so done with them..... But thanks for the input.
