i just wanted to know what people thought was the best motor oil to put into 5th gen preludes with a lil under 100k miles?

have you been using synthetic or not?

if you have, keep using it. Mobil 1, Amsoil, are my favs. if you've been using conventional, i'd keep using conventional. 100K is a little late to switch to syn, and might be a problem. w/ conventional oils i like castrol GTX.

i think the best oil for h22a is castrol rs 10w 60 and mobil 1 5w 50

i use only 10w 60 in my h22a

 

i ran synthetic oil (mobil 1) in my old H22 before i got a new motor and i use to go through it like crazy. Havnt ran any synthetic in my new motor. So your saying its bad to run synthetic oil on motors that have way more than 100,000 miles on them?

It's bad to <U>switch</U> to synthetic after 100k usually.

It depends on the condition of the motor.

 

yep - its hard to say whether a change to synthetic is safe at 100k.

Its not that synthetic causes problems, but it can reveal hidden leaks as it loosens carbon deposits.

If you stay with dino oil, Valvoline is pretty much the best out there. Valvoline is the only dino oil approved for use in some marine engines because it meets higher purity standards than everything else out there. with the abuse that marine engines see, thats been a good enough reason for me to use it.

My favorite synthetics are Redline and Valvoline Synpower, with a nod to Redline if you can afford it.

....i dont know about that...im going on experience from many wise mechanics with more years experience than my life and they all hate valvoline they all call it water
i just laughed when you said that because everytime i hear that brand i can see them all cursing it..nothing funnier than angry old men

way too thick for normal use. If you're running enduros all the time, might be justified--but if the manual is specifying 10-30 or 5-30 and you're running a 60 weight, i can't see that being justified in any sense.

i use a 40 weight when i'm on track sometimes...

 

Huh . . . I wonder if there is a special marine grade of some kind that the powerboat guys use. I'll have to look into that - its something I kind of grew up with since I live near one of the biggest boating areas on the east coast - maybe theres a little bs involved - I dunno
Interesting that the automotive guys don't like it . . .

 

Royal purple 10w-30 in the winter and 10w-40 in the summer

im living in germany and we have no speed limit on the highway so if im driving on the highway over 140-150 miles its better for my car drive a 60

No, with 60 you're not going to have enough oil pressure. A good synthetic at 5W-30 or 10W-30 isn't going to burn off easily unless you have problems. If you're that worried go to 0w-40 or 5W-40.

 

Motul here best oil Ive ever ran, and Ive tried almost everything.

 

Royal Purple #1

I run Royal Purple as well.

 

i've been running pennzoil high performance 10w30 in my car for the last two oil changes and i can thoroughly say i'm very happy. i used to be putting a quart in every 2000 miles, and no its a matter of 1/4 quart every 2-3000 miles. i used GTX the previous times and i'm happier with the pennziol.

 

i have been using mobil 5w20 but im thinking of switching to motul 8100 .

 

if you run anything higher than 40 than you are running dry in vtec just so you know...told to me by a honda technician

 

It's hard to miss with oil these days.... it's all pretty good. Quaker State / Penzoil is, IMO, the worst stuff out there, and it's still pretty good for street cars. The best ones I found are Redline or Mobil 1. Valvoline is good, they've always formulated for anti-wear, which causes some power loss in extreme engines.

Don't worry about switching between mineral oil and synthetic, you won't have any problems. If the API ratings on them are identical, then they are completely interchangeable.
