scott y Posted October 5, 2011 Report Share Posted October 5, 2011 Well, as Fall swiftly arrives, it's time to do my annual oil change...Not sure of the miles/km as I only go by my Patented GM oil life monitor. Since early Nov./2010 my oil life is 30%, lots of WOT,many hiway miles and just general use. The 94 STS shall receive 7l of Castrol GTX 10W30, a fresh delco oil filter,1/2 bottle of Lucas oil stab. and one 20 oz. bottle of GM fuel system treatment plus. The ol 94 should be good for another year(fingers crossed) 182,000 miles 292K km,Been doing this for 10 years and running STRONG! Link to comment Share on other sites More sharing options...
winterset Posted October 5, 2011 Report Share Posted October 5, 2011 Scott, Interestering.... I am curious. - Did your car ever have a HG job? What does the oil stab do? - I use synthetic & only put a few thousand mi. a year. I change yearly too. Do you change your coolant often? mine has about 109,000 THANKS Link to comment Share on other sites More sharing options...
scott y Posted October 5, 2011 Author Report Share Posted October 5, 2011 No HG changes as of yet,(that's why I keep my fingers crossed)I find that Lucas just provides the N* with a lubricant that current oils just don't have(zddp),I don't really know the advantages except 182,000miles can't be wrong. I also change the coolant each fall forgot to mention. Link to comment Share on other sites More sharing options...
Texas Jim Posted October 5, 2011 Report Share Posted October 5, 2011 Wow... my oil gets changed every 3 or 4 months... But I reckon I drive a few more miles than y'all do... Link to comment Share on other sites More sharing options...
scott y Posted October 5, 2011 Author Report Share Posted October 5, 2011 Based on your OLM,right Jim? I'm self employed so I have to travel a little more than most...but I don't change more than the OLM requires,that's just how "I" do it. Link to comment Share on other sites More sharing options...
adallak Posted October 5, 2011 Report Share Posted October 5, 2011 It is important to change oil at least every year regardless of low miles. Some quite aggressive chemicals accumulate in the oil which may hurt the engine. The saddest thing in life is wasted talent Link to comment Share on other sites More sharing options...

That's usually around 7,500 to 8,000 miles... give or take 500. Link to comment Share on other sites More sharing options...

I do not know whether Lucas in oil is harmful or not . Lucas products have solid reputation. The saddest thing in life is wasted talent Link to comment Share on other sites More sharing options...
rockfangd Posted October 5, 2011 Report Share Posted October 5, 2011 Heres mine. my 96 Deville. 195000 miles, no HG yet. No crankcase reseal. No anyting at all. When the OLM says change oil, I change the oil and filter. I dont use any addatives or synthetic oil. Just acdelco filter and 7.5 quarts of Pennzoil 10w30. I use no more than 1 quart of oil per oil change, I drive it hard with lots of acceleration and WOTs. This car runs excellent. Everyone has their own way but I like my money in my pocket. I figure if something ever breaks It doesnt owe me anything. Every year when it passes NYSI I say good for another year, and another etc...

mike5514 Posted October 5, 2011 Report Share Posted October 5, 2011 ZDDP is zinc its beneficial to prolonging the life of the cam valve assembly they removed it from oil when they went to roller rockers. I just started putting STP in my 97sls it suppose to have zinc in it. Maybe next time I will use Lucas.Mike Link to comment Share on other sites More sharing options...
cdgrinci Posted October 5, 2011 Report Share Posted October 5, 2011 ZDP is your last defense between metal to metal contact. ZDP levels have been reduced over the years due to the concern that zinc doesn't play friendly with your catalytic converter. A little zinc doesn't harm the 'cat' but high levels can; so it is not a panacea for happy motoring.

Ranger Posted October 6, 2011 Report Share Posted October 6, 2011 Mike, Zinc was not removed. They lowered the amount of it in the oil, not eliminated it..............yet. Link to comment Share on other sites More sharing options...
scott y Posted October 6, 2011 Author Report Share Posted October 6, 2011 Here in Canada(Bowmanville,Ont) at the local TSC Hardware store,they have 5l of Formula Shell in 5W30 and 10W30 on sale for $12.99 plus taxes...One hell of a good deal. Just about 1/2 price. Ithink that I'll buy 3 of those and my oil changes will be well looked after for both cars! Link to comment Share on other sites More sharing options...
JohnnyG Posted October 11, 2011 Report Share Posted October 11, 2011 Those oil additives are exceptionally good at one thing only, separating money from your wallet. You don't need to add anything to current SN/GF5 motor oil. Never underestimate the amount of a persons greed. Link to comment Share on other sites More sharing options...
