TUNING.......

Hello, how are my query good day, my query is the following I have a 2007 Pontiac G3 Model with Motor Dohc Etec II of 16 valves with 90000 kilometers and I need to make the tuning what kind of oil do you recommend as well as what kind of spark plug and how much they are calibrated by their attention a thousand thanks and greetings to all.

I personally recommend the AC of the SAE 40 oil, whether monotgraduate or multigrade, by the mileage and I do not recommend the synthetic oil, of the spark plugs if you want to see you splendid with your car Use some NGK of iridium, those insurance are going to last you from less 25000 km anted to replace them in addition to the fact that they are pre -heal where some specifications come, including the calibration of the spark plugs

CarlosGrinch's answer is good, but I advise you to look at the manufacturer's recommendations, there are the data you are looking for. With 90000 kms in three years your car has enough use. Take care of it.

I recommend Castrol Oil 20W 50 (made in the USA) since it is the one that meets the lubrication standards and exceeds them by 50%, its detergent property is very strong (clean all the internal dirt of the engine), of spark plugs, you can put as they already told you, the NGK iridium tx, only that they are a bit expensive, for a PT cruiser they were $ 540 (Mexicans) You can look for the NGK G-Power (made in Japan), Platinum fine point, they are cheaper and work very well ... although the spark plugs come, I recommend you recalibrate them, since in the packaging and transport, they could have received some blow and have closed their electrode ... Search on the NGK page the calibration for your car ... greetings ...

Hello thank you for your answers, I only have a doubt here in Mexico some friends of the Pontiac Club recommend me 10-30W OA more 15-40W and I also recommend NGK spark plugs; Already in Contre the calibration of the BCs of AC Delco 044 in case someone serves. I await opinions, thank you for your attention.
