I trust Castrol oil and the synthetic Edge brand is what my garage uses when I take it in for service so its also what I use at home.

I recently tried Royal Purple Full Synthetic Oil and you have to use a fully synthetic Oil Filter. This fits that recommendation perfectly.

I looked up the MSDS on this oil, and it is completely petroleum based.  It is NOT synthetic!  I was robbed.  I guess I will use this for my weed wacker.

Maxima products have always been high quality, I`ve been using these products for 20+ years and never hesitate to trust Maxima, this filter-oil is no different.....

Been using this a while and have no complaints.  Still reasonably priced at a time when every other subscribe and save offering costs as much as buying retail locally.  Seems like Penzoil lost much of its luster in the oil industry over the last 20 years or so but seems to be doing things right with their synthetic blends.  Back in auto shop our instructor used to illustrate how terrible Penz standard oil types were by dumping globs of it in water buckets.  Those Pens regular blends were real obvious once in water because its mass rarely held shape long.  These new synthetic blends hove come full circle and hold longer than most of the others I've recreated the experiment with.  My Jeep sounds much better with this Platinum  synthetic than any other brand I've tried.  Might be my imagination but I think it runs a littler cooler too.

I have been using this wonderful, flavorful, oil for 4 years and I love cooking with it.  It's fantastic on spinach and salads, and a little goes a long way because it's authentic oil.  There are so many fake olive oils out there so I'm really happy to have discovered this brand.  It's all organic, you can't go wrong.

I love this stuff. I made the mistake of buying the Giant Eagle brand coconut oil, the last time I ran out. You can definitely see the better quality with Viva Naturals.

If you drive a turbo VW or Audi, this is currently the best oil out there you can buy. I change it every 5,000 miles and never think twice about the protection my engine is receiving. If you have used Castrol or Mobil 1 in the past, you know that towards the end of the oil's life, the engine does not rev as freely until you go for your next oil change. Not with Red Line, my engine revs freely from mile 1 to mile 5,000 and trust me when I say I drive my car hard.

Great oil & good price. I have seen local auto-parts stores run specials on Castrol Edge High Mileage that are just as good - some including a filter.  Using it in my 2nd Gen Prius with 180K+ miles.  Works great.

The shipping information is a bit funky:  Amazon says I can get it in 2 business days with Prime, but the ad clearly states shipping is "usually 1-2 months".  You will probably wait a little bit to get this.  I did not have to wait as long as 2 months, but it sure wasn't 2 days either.  Order now if you need it anytime soon.

Very good oil at a reasonable price. If you have an engine with flat tappets you need the additives that are in this oil. They only call it racing oil because the government limits the additives in "regular" oil.

I have used the K&N, Mann, and Hengst. All are different in their own way: K&N was cheapest, light, made in USA, plastic ends which looked very good for a snug seal (many complain about the filter collapsing between OCIs which is unsettling), Mann was made in Mexico (doesn't mean a lesser quality because no one has proof - if you're so bothered by a Mexican filter, why are you driving a Mexican VW?) Had 55 pleats, and uses an Eco-top eco friendly foam seal - no rubber or plastic, Hengst is made in Germany which adds to the prestige, has 50 pleats, foamy paper seals on plastic base. I've used the three filters and would stick stick with the Hengst or Mann. Never had any problems with them using Mobil 1 Full Synthetic or Castrol Edge. If you have a turbo, use full Synthetic every 5000 miles (Mobil 1 is best most versatile if it's the European Car Formula 0W-40). If you have a naturally aspirated engine use blend or synthetic which is the most cost effective as your engines run cooler and can sustain longer OCIs of up to 5,000/10,000 miles, which means less oil changes and labor due to upgraded oil. Add 20% to the mileage if you're driving only highway at legal speed limits.

This is only my opinion and experience.

Ok, maybe 'life-blood' is a little bit of an exaggeration.  It is true, however, that your engine relies on lubrication so all those metal parts move freely and your investment(vehicle) gets you from A to B.  I've been using exclusively Penzoil Platinum 5W-30 on my vehicles for almost 10 years(as long as I've been doing my own oil changes).  Before I would just look for coupons to whomever was offering the cheapest 10-minute oil changes and repeat every 3,000 miles.  Then my eyes were opened to the miracles of synthetic oil and extended oil change intervals!

My vehicles for the last decade or so have all shared the same oil requirement(5W-30) on the oil cap and as stated in the manuals.  Yes, there are hypermilers out there who swear by thinner oils for even better fuel economy, but I stick with what the manufacturer recommends - for the most part.  I have found the Pennzoil Platinum to be a durable oil that in combination with extended interval oil filters(in my case Mobil1 Extended Performance) can provide adequate protection up to 10,000 miles.

My wife's car has almost 200,000 miles on it and has been on this 'diet' since new and runs great!  Since I do all the oil changes myself this limits me to around 2 changes a year on her car and once a year on mine(shares the same engine, but different models).  Again, the oil is just half the equation.  You need a quality filter that is designed for higher intervals.  Even the manufacturers have said that every 3,000 miles is unnecessary under normal driving - and that's with cheapo filters and Dino-oil(conventional oil).  With a premium filter with double the holding capacity and synthetic oil I don't believe 10,000 miles is unreasonable.

Disclaimer:  This is purely my opinion and not advice of an automobile professional.  I'm just a regular guy who has a decade of experience using this method on multiple vehicles.  Perform at your own risk!

Finally, I like the 5 quart jug versus the 6 pack of individual quarts.  Much less expensive and less plastic to go in our landfills(please recycle where available and dispose of your old oil at a proper facility and not down the storm drain).  5 stars for premium protection at a great price!

Not much you can review negatively here. Mobil 1 high mileage full synthetic has been in my car for years now. I like this 4 pack because you can get a bulk discount if you wait for the price to drop slightly. Came in a nice small box too so I keep the oil in there until I use it.

I have been using Spectrums brand for a year now. I use it for hair, cooking, oil pulling, as a body moisturizer, and as a air fresher in my oil burner. Recently I made the mistake of trying other brands. I will never do that again. I'm from the islands so I know the true quality of unrefined coconut oil. I promise Spectrums Unrefined coconut oil is honestly the best quality, texture, and organic scent. I will never venture out again.
