stupid question but want to know anyway. my car has 101k so does it need high mileage oil or regular will do? my friend told me to go full synthetic but some say its not necessary. any advice? thanks

personally id use high mileage. iv put 5w 30 synthetic in a motor with 155,000 on it and the front main seal started leaking so i added a lil 10w and it slowed it down alot. if all ur rings and seals are good its fine to use synthetic is what i was always told.

IMO it won't matter. My Father's 94 EJ1 with D16Z6 has 270,xxx miles on it and he just uses regular Castrol GTX 5W-30 and its fine. My old D16Z6 had almost 200,000 miles on it when I sold it and I just ran Regular Castrol GTX 5W-30 and I never had any problems. It won't hurt anything if you do run the high milelage oil either though.

As for Full Synthetic. Again, thats your call. The engines broke in so it won't matter either way. I change my oil every 3,000 miles to keep the oil clean so I don't pay for expensive synthetic.

Will it mess up my car if I put royal purple oil in it ???

It'll mostly mess up your wallet.
But no as long as it's the right weight it'll be alright.

Why would that even be a question? The engine calls for 5-30 or 10-30, depending on where you live. Follow the factory recommendations.

Really another one of these threads? Do you're research there are literally thouands of these everywhere.

The question you're asking is opinionated, nothing technical. Use whatever fits your budget.

Agree.

Look. Ultimately, you have just over 100k on a Honda that will easily go over 200k miles. Just pick one and stick to it.

I have 273k on my D15 and just run 5w-30.

A good oil filter is far more important than the type of oil in this situation.

Just buy an OEM oil filter and don't worry about any aftermarket stuff.

If your engine burns oil (as most older Honda's do) full synthetic will burn faster than conventional oil. Some people prefer 10w/40 conventional to slow down burn off. Products like Castrol GTX High Mileage oil is no different than any other oil other than it has an additive to swell rubber gaskets and help prevent/stop very small oil leaks.

This "which oil" topic really has been beat to death over the years and it's up to the individual to follow factory recommendations (5w/30) or not in this case.

It won't matter, unless you like spending more money for nothing.
