SignUp Now!Getting my car ready for the Las Vegas heat. Thinking of using 15w-40 and a Lucas additive. Anyone else using this type oil? Thoughts/comments.......Thanks,....Cesar
What is the advantage of running the heavier wt oils? Most engine wear occurs on start-up especially with cars that sit for a while between drives. Factory specs are 10w30 -10w40 right? Just curious? .......
Nick,
........ I assume the higher wt oils produce better film strength in higher boost / rpm situations. Good to know. If the is no harm in running the 15w oils and it gives you increased performance with more boost, it would be a sound choice. Do you recommend a larger oil filter or just a good quality std size (wix, purolator, etc)

Nick,
For our overworked v6s :biggrin:, what low detergent 20w50 do you like?
One last thing, with a stock front cover what's your feeling on a high dollar billet filter without an anti-drain back?......Thanks,........Walter
For years we have used and promoted Valvoline Racing oil and used EOS, and now ZDDPlus, with excellent results which means hundreds of 9 sec. runs and bearings are still excellent. :biggrin:
As far as the billet filters, I personally have mine remote mounted upright, but know of other Buicks with them in the stock location with no issues.
