2004 GT Running Royal
Hey I was wondering if anyone know anything about royal purple oil, good or bad. I've been running it in my car the last 3 oil changes no problem. I got another car recently and have just been letting my mustang sit and I was going to drive it the other day and checked the oil and it had only a quart of oil in it. I haven't drove it in about 3 weeks and last time I drove it there was no smoke and there are no spots in the drive way and it was holding oil pressure. It only has 70,000 miles on it anyone have advice? Any chance it could be the oil I'm using? I'd rather fix it myself then pay a shop to do it.
