I decided to keep this car, until it dies and experiment with additives. My plan is: change oil filter at 3500 (3220 now), then another at 4500. Then oil change at 5500. Will put in Liqui Moly MoS2 Antifriction 10W-40 oil, with no ARX, keep it 3000 miles and filter change every 1000 miles. Then change to same oil and last bottle of ARX, keep it for 3000 with filters every 1000. Change again, same oil again, keeping 3000, filters every 1k miles. Then going back to normal diet. Depending on the time of the year will put Lubro Moly 10w-60 or 0w-40 both syn, will be good for 10k miles, planning to change filter at 5k, will probably use Bosch. If oil burning will still be severe, with 0w-40 winter oil, might switch it for Nippon 0w50 Full Syntec Japanese oil (will it glow in the dark after Fukusima blew up?
. Also planning to add Cera tech additive which is claimed to be better than Moly and used onces in 30k miles
Plus will add some valve cleaners and fuel system cleaners. Added about 4 fuel system cleaners, since got car (like Shell V-power, Chevron, and so on.)Last added was Lubro Moly Valve cleaner, which cleans fuel system too. Will inform about each additive. Right now car has 137k+ miles, after heat up runs like a clock, except for oil burning.
Also planning to do little tune up soon. Change air filter to KN&N high flow, fuel filter change, PVC valve again, and transmission oil to Lubro Moly Syntech 75W-90 + some moly for gears. Just looked underneath my car yesterday, it doesn't looks that anybody ever changed oil there. Might be trouble to unscrew drain and filler bolt, they look corroded and hard to take off. I have a question. How much oil to I put to this specific Gearbox? Girl at Napa told 4.4 quarts, but she was confused between Clutch fluid and Gearbox oil. It seems to much oil for transmission. Also might go to Europe next spring and try to get Liqui Moly 5W-50 Molygen Oil, as I know looks toxic green, and it's syntec with Moly. Found one and Ebay at GB but it's 15w-50 and 4 liter and they don't ship to USA. Also Found same but 5w-50 and Singapor, not sure about delivery and it cost there 96$ for 4 liter jug!!!
