one year ??? man that,s way too long ,, how many miles ?? i have been working on hondas for many many years and i have found that the best way to have the engine reach 500,000 miles is to regularly change oil + filter every 3000 miles , no need to use syntetic, 5w-20 if around zero or below temper in winter .. 10w-20 in warmer winter climate

 

About 10,000 miles. It's not too far off from honda's recommendation of 7,500 miles. Also, when I change the oil filter at the 6K mark, I add about 1/2 to 3/4 quart of oil to replenish what's there. Mobil 1 is cheap up here less than $3.00 a quart sometimes even less with rebate so I just go with their 5w-20 with the latest gf-4 formulation. Since its synthetic I think it can go longer. Amsoil after all claims 35,000miles with a 6 months interval.

 

iove trust me on this one,,, if you want ur engine to last and last like the energizer bunny replace oil and filter every 3000 miles. .....i rather see people use regular motor oil and change it two times to keep it cleaner than use syntetic and change it once ,,,,,think about it which engine will be cleaner 2 oil changes in 6000 miles or 1 oil change every 7500 miles ....
