I've ignorantly been using 5-20 Royal Purple or Mobil 1 Synthetic in my L since '01. It gets sunny day driver / road course use. What weight engine oil are you guys using? 10-30? or thicker? any issues?

Road course sessions are only 20-30 minutes.

If you have an oil temp gauge, and the oil is not getting too hot, there is no reason to think that a truck used on the track needs any different oil from a daily driver. And if the oil is getting too hot, the solution is a cooler, not heavier oil.

But what I would be worried about is losing oil pressure on long corners.

 

I whole heartedly aggree with Tim, I tossed in some RP 5w-30 and a K&N filter for the road course, but anything is fine, just change it before your track day if you wanna be a little **** like I am, you don't NEED to run anything exotic, it won't hurt but I doubt it will really be much better than any other off the shelf full syn that is fresh.

As for losing oil pressure in long turns.....ehh I have yet to hear of an L pulling enough sustained G's to do it, but it is very plausible. Quite a few L owners have ALOT of open track miles and no problems though.

 

Why would you think that using 5W-20 in an engine where 5W-20 is recommended is ignorant???

 

I've never heard of it either, but I don't know of anyone who runs a quick-acting oil pressure warning lamp either. Ruslow has an Accusump, so he's not going to get oil starvation.

I have an Accumsump waiting to install. It's definitely not a must-have, but you know me -- I'm all about making a bulletproof truck. In addition to preventing oil starvation, the Accusump acts as a pre-luber, and allows you to run the oil a little low (for the benefits of a windage tray).

 

Yuppers, I looked it up ... Next to "****-RETENTIVE" I found Timmay's pic.

On my built motor they say the rings are a tad looser than the stocks so there won't be as much pressure so the builder (BISHOFF) suggested that I go with a bit more weighty lower end oil.

The 5-20 oil was primarily to meet the CAFE requirements according to what I heard

My oil capacity is right at NINE quarts now......

 

The weight of oil in designed into the clearances of the engine.IF they are tight then use a thinner oil and visce versa.Oil starvation is not from the weight of oil as it more to the location it is in the pan.A heavier oil will wear a motor faster if all you do is cold starts and not let the oil get to temp.there have been tests done and oil takes the least amount of hp and lubes the best in the 180-195 range and guess what that is wear the thermostat is set at!As oil starved that these are on the upper end I would not even think of anything over a 15w for cold start.Stan

 

Sorry to go off topic but, Stan I have been calling you, could you please give me a call or PM.

Thanks
