Red Line synthetics are #1, Mobil 1 is more economical , excellent,and what I use in street cars, Castrol is best of the conventional oils. Best gear lube bar none is Red Line 75/90 NS - ns being Non-Limited slip , perfect for transmissions - limited slip additive is hell on synchros. We did extensive (and expensive) testing on all oils when I ran showroom stock and SCCA races. Red Line always, always beat the pants off of everything else - even at 250 degree oil temp we never lost oil pressure or hp. We did all of the testing, the little machine that measures wear on steel rods using different lubes , sent used oil out for analysis, etc... Downside of Red Line is availability and the cost - almost $8/qt.! Once I lost a head gasket in my Formula Ford during a race with Red Line in the car. Pumping coolant into the crankcase. I figured it was curtains for that motor anyway, so I finished the race to get the points. Pulled the motor down and there was virtually no wear or damage to the bottom end. The coolant was beading up on the cylinder walls like they were waxed! Great oil. A few years ago I was sold on Royal Purple , it made a few more hp on the dyno and seemed great. Then I lost a few engines and checked into it. Oddly enough, the first few dyno pulls gain power, then we kept pulling with the same oil and started loosing power with Purple ! Put in Mobil 1 and did the same tests - no problems. That was it for the Purple! And, they were sponsoring my car at the time. One final note: I have also had great luck with Lucas Oil Stabilizer in older cars that have "issues". Really good stuff in trannies and engines, I use it in my tow truck that was pronounced dead 6 years ago, but Lucas has kept it alive. The truckers swear by it as well. Good idea for older engines. Just my $.02.

Engine oil survey Colin. Your comments echo the comments I have heard about red line. I do use the Red Line products on my gear box and rear end on 6S2166 which is primarily an open track car. Recently I had the engine rebuilt due to engine failure. More about why later. The engine builder requested that I use valvoline racing 10/30 for the foreseeable future. He mentioned that it is excellent oil and had a low foaming quality for engines that run at high RPM's, and make rather large HP. I granted his request for the dyno time and the first 10-15 hours of drive time. Recently I changed to Mobil 1 10/30 and here is why. 2-3 years ago Pete Geisler invited me to attend the Charlotte Auto Fair event with him. While there pete introduced me to a customer that is the engine builder for a current Ford based NASCAR team. Not being a NASCAR guy, I do not remember the exact team, but his brother is the fellow that rebuilt my engine in 2166! Small world. So I innocently ask him about the oil his team uses..................he gives me a nice look knowing that I am just an enthusiast hoser and politely says that some people would lay him A LOT of money to know exactly what they use and what is in it! He then on went on to add that they formulate their own oil for team use but, they recently had a new car be introduced so during the dyno time and first track sessions they ran two identical cars, one with the team oil and one with Mobil 1. He claimed that the HP and wear results of Mobil 1 came within 1% of the team oil. Case closed for me. Incidently, I just got the car back from the SAAC Vegas event where I had the pleasure of hammering it hard 5 straight sessions and the car never seemed to breath hard. In fact, due to the weather and a large radiator with integrated oil cooler, I had a hard time getting the oil temp up to a nice temp.....that does not seem to be the exception with Mobil 1. To add intrigue, my engine first broke 2 years ago when a roller lifter ( Iskendarian) decided to collapse and rub down a cam lobe. The only recent change I had made was switching from Mobil 1 to another big name synthetic just to try something different. And I am talking about changing the oil and the motor braking less than 1 mile later. Did it cause the engine to break..probably not, but I won't use anything but Mobil 1 post break in. Colin. One more question. I have a 1998 Saleen S351 that in the owners added paperwork from Saleen, that advise using routine 5/30 oil...non synthetic. The car has 9900 miles. Is the any logical reason I could now now use Miobil 1?

Dan, I don't see why you couldn't use Mobil 1 10/30 in the Saleen. I use it in all of my street vehicles, and it is factory fill for a lot of mfrs, presumably before those motors are "broken in" also. I have a customer who is an engine builder at DEI. He echoed the same comments your guy did. When we were really testing oils, Mobil 1 was not that great. But a few years ago they changed it, and wow, what a difference. A side note - Castrol Syntec is terrible oil. FYI! Castrol GTX is excellent oil. Go figure. A lot of engine builders swear on conventional oil. One has to wonder if this is some form of constructing job security?
