I'm looking for a good break in oil and race oil for my Formula Vee/FV1200 race car. It is powered by a modified (but no turbos, nitrous, or anything crazy) Volkswagen Beetle engine from the 60's (1.2L, air cooled, four cylinder, carbureted, 6500 RPM shift, 4L oil capacity). I run six, three day events per season. OCI is relatively short, I will changing the oil and filter (Napa Gold or possibly K&N) before each event (for Friday and Saturday morning practice), and right before qualifying on the Saturday and using that oil for qualifying and three, fifteen minute races. Over the winter I will be getting the engine rebuilt (new pistons, rings, bearings, gaskets, etc.).

I am looking for a good conventional oil to break it in on during one pre-season practice day (I was thinking Valvoline), as well as my regular race oil. Everybody seems to use 5w30 for whatever reason, but I was thinking a 30w would be better suited. I can get a 5 gallon pail of Royal Purple 30w or 5w30 relatively cheap. I also have 22L of Mobil 1 10w30 that I could use. Amsoil is somewhat available (standard issue 5w30 and 10w30 @ Canadian Tire) but doesn't seem to make sense for such short OCI's and it's ---- expensive so I'd like to use the RP or M1, but if something is really much better for this application I don't mind spending a little more. Over the winter I will be obsessing about finding ways to reduce oil temps as much as possible (cooler engine = much more power) so any oil that helps accomplish this would be great, although protection is the most important. Sorry for the long post, just trying not to leave out any details! Thanks for the advice...
 
P.S. I should add that these engines tend to suffer from a little oil consumption - but it's not a big deal since the OCI's are short and it's topped up every session.
 
Since you already have 22L of Mobil 1 10w30 go with that. Especially since you are going to rebuild the motor during the Winter hiatus. With such short oil change intervals just about any oil will work. A lot of people will tell you that you need thicker oil but don't forget you are racing this engine. That's why most of your competitors are running 5w30. To squeeze every last horsepower out of the flat-four.
 
Interesting...could somebody please help me understand this...in theory, shouldn't 5w30 and 10w30 of the same brand be of the same viscosity once up to operating temperatures? I know this isn't always the case, but if somebody could explain this I would appreciate it. Besides, in the case of Mobil 1, isn't their 5w30 thicker than their 10w30 (based on what I've read on here)?
 
Both should be within the same range at operating temp. The 5w30 is closer to operating temp viscosity at startup. One hates to split hairs but until the engine gets to operating temperature the 5w30 should be thinner than a 10w30. Allowing a little more power during this period. I can't believe I am doing this. This splitting of the hare. My previous post was only posted so you would not go out and waste your money when you already have the right oil. For street use I believe most run 30w or 15w40 in this motor. Don't worry If I am wrong someone will be here to correct me.
 
As per Camu Mahubah's request (so I don't get accused of "showing off" e.g. the Bentley thread, hahaha) here is a pic...

I just bought it, over the winter I am stripping it down completely, getting the engine rebuilt, getting the bodywork painted, all new dzus fastners, re-doing the wiring etc. etc. etc. It's fine as it is, but I'm a major perfectionist.

I just moved up from these (I'm only fifteen)

...and a vid (they go pretty good) I'm in second in this video, I later passed for first place...

I am not nearly educated enough to be recommending an oil in a race car. I would recommend some one is though, namely, Terry Dyson at dysonanalysis.com
