i been using honda oem 10w30 oil, i was wondering if i can change to castrol synthetic or mobil1 and give synthetic a try? my motor is a 93 JDM h22a motor with around 50K millage on it.

hu

50k is an exvellent time to switch to synthetic. Not too early or too late. I recommend Mobil 1 (extended drive) which is a full synthetic.

I run the basic mobil 1 5w 30, in the same motor you have, with about the same miles.

you should probably be running the stock 5/30, unless it's SUPER hot where you live, especially at that low mileage.

my engine get pretty hot and i drive hard and go to races a lot so probably 10w30 mobil1 synthetic is good. planning to go for full royal purple 10w30 too.

i run only mobil 1 10w30 since day 1. car has over 117K miles and doesnt burn a drop if i dont drive like an anus

Royal Purple even though the damn stuff made me throw a bearing... or rather... the previous lack of oil and carbon buildup which burnt up when I switched did it... but whatever =P

just make sure when you switch...thats it..no going back to conventional or even switching brands...so pick one oil and buy it the rest of that engine's life.

the manual specifies that 10-30 is fine for areas w/ temperatures above 30 degrees F (or around there).

the cold flow characteristics of 10-30 should be fine for cold start protection in an h22.

I heard that Penzoil is bad for motors. Is this BS?

yeh penzoil is not very good, it like a cheap oil. i have heard bad thing about it. mobil1 is a way better brand, in fact Genuine Honda oil is create by mobil1.

phateless

i work at a dealer, and i get 5 liter jugs of motul 5/30 for $20, so that's what i use. this **** is just as good as mobil1 if not better. 100% synthetic (group IV base stock)

Uh.....this is false. Do some research for yourself and you will see. If you have an oil leak, synthetic may make it worse due to the fact that it flows a lot better. Things like this give it a bad reputation when it is actually just lubricating better

Royal Purple for peoples with deep pockets.
Mobil 1 for average peoples.
Redline Oil for extreme enthusiast?

Sorry to thread jack, but I'm in the same boat and I figured I'd ask in this post. I have a 96 Prelude S, (sohc f22a1) with 91,xxx miles. It's completely stock, and is my daily driver. I have been thinking about switching to synthetic, but I'm not sure if it's too late.

I currently use Valvoline MaxLife 5w30, which I change every 3 months. I don't have any leaks. I'm about to have my cam, crank, and balance shaft seal replaced along with my timing belt, water pump ect...

Thanks,
Del

i switched my accord to synthetic at 150k, my gsr at 120k, and my ls at 173k. no problems.

^ Supposedly, you can switch to synthetic anytime a car is not new. IMO, its never too late to benefit from synthetic oil.

They say not to use synthetic oil on a new car from the factory. Does anybody know why MB puts Mobil 1 0w-40 (on AMG) as standard fill straight from the factory???

hu

I think CGags is correct. Once you switch to synthetic you cant go back to conventional oil.

CivicSiDriver02

Well normally conventional dino oil is used during break in to allow the engines internal parts to wear together. If you use synthetic you are slowing down the wearing process and you will not get optimum performance. AMG engines are built by an outside source and are hand assembled and broken in prior to being put in AMG Mercedes.

jdmb20a

real old engines will probably be more likely to have small oil leaks, at gaskets, piston rings, seals, etc... lots of blowby of oil, oil in the gasoline, etc etc...

if your car doesn't leak oil, and you probably don't burn too much, don't worry about it. but on brand new and high mileage motors, I've always read to stick with non-synthetic oil. when I have high mileage motors, I use low grade average 10-30 oil (no additives) and a quart of lucas (makes oil pressure skyrocket, coats everything better, especially for cold starts). don't mix lucas with synthetic, or extremely good oil with lots of additives, so I've heard. just with the cheap stuff.

purple royal is definitely what to use at 50k. or any synthetic oil is pretty good next to your average 10w-cheap oil.

Google owns you...
Just did a search and this is what Quaker State says:

Myth #4

You can't switch from synthetic oil to conventional oil or vice versa.
You need to start with a synthetic blend for a few oil changes before moving to full synthetic oil.
Once you start using synthetic motor oil you cannot go back to conventional oil.
Synthetic and conventional engine oils can't be mixed, or else they react and cause engine problems.

Fact
As long as the synthetic motor oil product and conventional motor oil product meet the viscosity and performance requirements outlined in the vehicle’s owner’s manual, you may interchange them with each other.

K-Spec

here's some more myth busters from Mobil1's site.

Myth:
You should break in your engine with conventional oil, then switch to a synthetic oil like Mobil 1.

Reality:

You can start using Mobil 1 with SuperSyn Technology in new vehicles at any time, even in brand new vehicles. In fact, Mobil 1 with SuperSyn Technology is original equipment (it is installed at the factory) in:
Aston Martin
Bentley Amage and Bentley GT
Cadillac CTS, XLR, SRX and STS
Chevrolet Corvette
Dodge Viper
Mercedes-Benz AMG vehicles
Mercedes SLR
Mitsubishi EVO
Pontiac GTO
All Porsche vehicles
One of the myths that surrounds synthetic oils is that new engines require a break-in period with conventional oil. The fact is, current engine manufacturing technology does not require this break-in period. As indicated by the decisions of the engineers who design the high-performance cars listed above, Mobil 1 can be used starting the day you drive the car off the showroom floor.

Myth:
I need to flush my engine before switching to Mobil 1.

Reality:
No special preparation is necessary when switching from conventional motor oil to Mobil 1 or Mobil 1 Extended Performance.

Myth:
Mobil 1 will leak out of the seals of older cars.

Reality:
Mobil 1 does not cause leaks. In fact, new Mobil 1 was tested in dozens of industry standard and OEM tests to prove its seal performance. It is fully compatible with the elastomeric materials from which all automotive seals and gaskets are made. If an older engine is in good condition and does not have oil leaks, Mobil 1 provides the same advantages as when used in a new engine. ExxonMobil recommends taking measures to repair the leaks, then using Mobil 1. ExxonMobil also recommends following the automobile manufacturer's manual for the proper oil to use.

oh and i read somewhere that quaker state is owned by penzoil...
