My daily driver is an 2002 E46 M3, so I'm familiar with the Castrol TWS 10W-60. But I believe it maybe relabeled as Castrol Edge "SuperCar" oil now. " The Castrol 10w-60 SuperCar is available at my local Autozone.
If my car did have stuck rings, or even any type of oil getting past the rings in the combustion camber, would a compression test show me that? or even a Leak down test (which ive never done before)
The Gallardo is very Much an Audi/VW product, not sure about the actual engine block, or transmission but the electronics, interior buttons and switches all have Audi part #'s for the most part.
Yes that's me in the video, I had been awake all day waiting for the car to arrive, it was late & freezing outside, I was overwhelmed with everything an didn't know what to really say to the camera, but I'm still glad to have it on video. I was so much in awe that I didn't take one picture on delivery day.
Lastly I know everyone has there "favorite" oil brands but as far as oil weight I'm torn between 10w-60 (large #'s spread will shear down?) or a Less aggressive 15w-50 oil that maybe more shear stable, as my car will only be driven in the warm summer months, an put into storage during the cold ohio winter's ,...……….how thick can the oil viscosity be for cold startup protection during the Ohio summers, 10w, 15w, 20w. I don't know
Mobil-1 15w-50 at short OCI's, maybe even 1k-2k. You likely have some stuck/coked rings. And 5w-40 for your engine is inadequate during summer driving. Mid (and rear) engine vehicles tend to have higher engine bay temperatures than front and front-mid engine vehicles. M1 15w-50 is readily available in 5qt jugs.
My 1999 911 3.4 H6 (in a significantly lower state of tune than your lambo, mind you) comes recommended from Porsche for 0w-40 oil. Which ends up being fully inadequate even for street driving here in Central FL from March through November (with oil pressure regularly dipping below recommended levels and consumption of 1 quart every 1500 miles). So, I've seen great success running robust dual-rated SN/CJ 5w-40 diesel oils like Rotella T6 (actually both 0w-40 and 5w-40), Mobil Delvac 5w-40, and Chevron Delo Syn 5w-40(with HTHS's of 3.8-4.1, up from M1's starting HTHS of 3.5, which quickly moves toward the 2.9 of a 5w-30 oil....YIKES). Engines run smoother and burn/consume zero oil now even with spirited driving bracketed by radiator crushing stop-and-go traffic. I have run M1 15w-50 in mine and, while great when fully warm, warm up time was rather extended over even 5w-40 and the engine was pretty sluggish until fully warm (which often took more than 20 minutes of actual driving) whereas the 5w-40 is fully warm with optimal oil pressure after only 10-12.
Any std gasoline-only-rated 40 weight will likely not be heavy enough for you; 5w-40 dual rated oils as noted above should be your absolute baseline, with a min HTHS of 3.6 and above. I think M1 15w-50 is a cost-effective stop-gap experiment on your way to something possibly as heavy as Castrol 10w-60. I would try 15w-50 first.
