This is LE 8530, which has been replaced by 8531. Previous UOA of 8130 concerned me with high sodium reading. 8130 has about 20 ppm Na, and 8530 has none. I decided to add 6 GM walnut shell veggy pills to the coolant a couple of weeks after filling with 8530. I think it is helping with the HG leak. Anyone know how often to add the pills to the coolant?
2008 Avalanche 5.3L iron block.
LE 8530 Monolec SPB (synthetic petroleum blend) 5W-30
PureOne oil filter.
OEM air filter.
Fuel unknown (probably whatever is cheap). LE L-X fuel additive every 1000 miles.
This is my daughter's truck. A rear main engne seal leak is developing already. Gotta love a GM product!
