Mobil-1 10-30, I spoke to the M-1 engineers regarding the Zinc thing and the "wear issues" They tell me that M-1 is fully compatible with the LT5 engine and the additive package will fully protect just as it did when it became factory fill in 92.
Again - this become a personnal thing to each car owner, his beliefs, what they read and who they trust!!! Don Yoakem 91-#267 Dak Red Met. ![]() |

Hi guys. I've read all you messages related to engine oil advice and I'd like to ask you a few questions.
I purchased my ZR-1 3 months ago and I had the oil immediately serviced, that is, engine oil and filter replaced. As I wasn't well read on this matter I put 10W60 Shell Helix on it and a Champ Oil Filter. I've made around 3,000 miles with the car (27,000 on the odometer when I bought) and I'm seriously thinking about servicing the oil and the filter again. Do you think this 10W60 oil couldn't be suitable for very hot summer temperatures (over 100 ºF in my country)? As fair as I know 10W60 oils offer better protection in hot environments compared to 10W30 ones. But it's also true that the oil temperature in the LT5 is slightly over 100 ºF most of the time rolling. Many thanks in advance. |

Many thanks for your answer Jagdpanzer.
Definitely I'm changing the oil of my sooner the sooner I can. As it's not possible to get fully synthetic 10W-40 engine oil here, I'll ask a friend in the US to send me some gallon bottles of 10W-30 Mobil 1. I've already received a couple of Bosch oil filters, both PCV valves and a K&N air filter I'll have installed the day we replace the oil. Using 10W-60 may be one of the reasons for the car not to run very fast until it reaches 2000-2500 RPM. I don't know how to explain, but if you hit the gas it doesn't accelerate progressively, it feels as if there were some kind of jamming or something. Maybe the ignition system is not working properly so I'm thinking about changing spark plugs, spark plug wires and even the distributor rotor. |

My point is, I don't think the oil has anything to do with the torque below 2000 or 2500 rpm for a couple reasons: It has more to do with the design of the plenum, etc as to where the torque curve "kicks in". The effects of high viscosity would be more prevalent at higher rpm than at the "off idle" speeds. So, way down low the effects would be much less severe. As for changing the distributor cap and rotor on the LT5...it will be hard to do, as the ignition is 100% solid state. - A spark control module under the plenum handles most of the timing chores with inputs from crank position sensor. ![]() As for Amsoil AMO (preferred by Marc Haibeck - one of the ZR-1 gurus), or Mobil 1, just say the word, and I or most others here would be happy to send ya a case, if your US contact can't be reached.
